Basic Information

What is a German Equatorial Mount?

In the northern hemisphere, stars appears to turn around the polar star (the north celestial pole) making approximately one rotation per day. This is called diurnal motion and occurs because the earth turns on its own axis once a day. The equatorial mount is a platform which is designed to rotate parallel to earth’s rotational axis.

Basic movement of the AXD Mount

Every movement of the electrically driven AXD Mount is fully controlled by the STAR BOOK TEN hand controller. The mount will perform smooth and accurate movements when each component on the mount is balanced correctly. An unbalanced mount may cause vibrations and can result in tracking errors or failure of rotational mechanisms. Make sure that the telescope is well balanced. Refer to page xx on how to balance the mount .

CAUTION

Do not rotate the mount manually without loosening the clamp levers.

The AXD mount has clamps which allow you to rotate the Right Ascension (R.A) and Declination (DEC.) axes freely for quick set up and compact storage of the mount. Remember to tighten the clamp levers when you use the mount. The clamp levers should be loosened to protect the inner gear train for storage and when you transport the mount.

CAUTION

Never connect the STAR BOOK cable to other equipment such as a PC.

This could result in electrical shock, fire, or damage to the equipment. (The specifications of the STAR

BOOK cable are not compatible with RS232C connectors.)

CAUTION

Be careful not to bang the mount against other objects. This could damage the gears and bearings.

3. Tighten the lock knob on the inside of the AXD half pillar to secure the AXD mount.

Tips on Assembling the Mount

Generally equatorial mounts are heavier on the declination axis side. Because of this feature, placing the equatorial mount so that its declination axis comes directly over one of the tripod legs can make the equatorial mount most stable when you use the equatorial mount for a north (or south) latitude of 50 degrees and lower. However, the balance of the equatorial mount may vary if the equatorial mount is used in latitude higher than 50 degrees. This may result in shifting the center of balance to the opposite side of the declination axis depending on the location of the loading equipment. Change the position of the tripod legs so that the equatorial mount becomes more stable in such a case.

III. Attaching the Counterweight

The counterweight bar is in the declination body.

CAUTION

Be sure to handle the counterweight carefully as it is a very heavy item.

1. Loosen the counterweight bar lock lever to draw out the counterweight bar.

2. Remove the safety screw on the end of the counterweight bar. Loosen the lock

3. Attach the counterweight so that the lock lever on the counterweight is on the far side of the safety screw as shown in the figure.

4. Tighten the counterweight lock lever and replace the safety screw to screw it down on the end of the counterweight bar tightly.

IV. Attaching a Saddle Plate

There are different sizes of threaded screw holes on the mount head of the AXD mount as shown in the drawing below. Choose the screw holes that are appropriate to your saddle plate that holds the telescope tube.

Balancing the Equatorial Mount

Why Balance the Mount?

The Vixen AXD mount is a German equatorial mount, in which the rotating RA axis and rotating DEC axis cross each other at right angle. The axes are rotated by using the movement of both axes to get maximum stability and limit the stress on the gears. If the equatorial mount is in an unbalanced state, it will increase stress to the gears and this could result in damage or erratic operation.

Precise slewing requires a high level of accuracy in rotation of both axes and is important in eliminating stress to the gears. Make sure to balance the equatorial mount properly in RA and DEC accordingly.

CAUTION

Take care not to drop the optical tube assembly as it could seriously damage the equipment or lead to injury.

Pay close attention to the security of the telescope tube and do not excessively loosen the lock knobs on the equipment.

Balancing the Mount in Declination

1. Loosen the R.A. clamp lever while holding the counterweight bar and turn the telescope tube until the

DEC. axis comes to horizontal as shown in the figure 1-2. Tighten the R.A. clamp lever and loosen the

DEC. clamp lever.

2. Release the telescope gradually to see which To determine the balance point, loosen the lock way the telescope rotates around the declination knobs that hold the telescope tube to the saddle axis. If the telescope tube starts rotating as you plate (or lock knobs on the tube rings) and slide release, it shows there is an imbalance in DEC. the telescope tube either forward or backward until it remains stationary.

PREPARATION

3. Tighten the lock knobs (and the safety screw if any) securely to hold the telescope tube in place.

4. Tighten the DEC clamp lever to finish this adjustment.

Loosen the R.A. clamp lever while holding the counterweight bar and turn the telescope tube until the

DEC axis comes to horizontal as shown in the figure 1-2.

Release the telescope tube gradually to see which way the telescope rotates around the R.A. axis. If the telescope tube starts moving by its own weight as you release, it shows there is an imbalance in the R.A.

2.

While holding the counterweight bar, loosen the lock screw on the counterweight so that it can be moved to a point where it balances the telescope tube. This is the point at which the telescope remains stationary when the R.A. clamp lever is loose.

If your telescope is light in weight, the mount may balance without the supplied counterweight. (The extended counterweight bar itself can act as a counterweight.) Retract the counterweight bar for further balance adjustment.

3.

Tighten the lock screw on the counterweight to hold in place. Tighten the R.A. clamp lever on the mount securely.

CAUTION

Do not move the counterweight too much in balancing. This could damage the telescope tube or lead to injury.

Tips on proper balancing

With balance arrangements below, the AXD equatorial mount can balance a counterpart weighing from 2.7kg

(6 lbs.) up to 30 kg (66 lbs.)

From 2.7kg (6 lbs.) to 4.3kg (9.4 lbs.) From 5.9kg (13 lbs.) to 7.2kg (15.8 lbs.)

Chapter 4

AUTOMATIC SLEWING

AUTOMATIC GOTO SLEWING

The moon and bright planets are found readily in the night sky as you can locate their positions with ease.

However, less bright planets, nebulae and star clusters are dim and mostly invisible with the unaided eye.

Even if you know where these dim and blurred objects are in the night sky, it often takes time and effort to look for them. The automatic Go-To slewing with the STAR BOOK TEN will assist you in locating celestial objects easily and quickly.

Startup Procedure

Locating the Mount

Point the mount toward the north celestial pole in the northern hemisphere (the south in the southern hemisphere) so that the R.A. axis on the mount is parallel with the axis of the celestial sphere in your observing location. (Detailed instructions below)

Setting Home Position

Loosen the clamps on the R.A and declination axes and move the telescope to the home position by hand. Point the optical tube to due west horizon in the northern hemisphere (due east horizon in the southern hemisphere) to fix the home position. (Detailed instructions below)

Two Star Alignment

Select two stars from the list in the STAR BOOK TEN to align the telescope. The more alignment stars you select, the more centrally located the target objects will be in your telescope

’s field of view.

(Detailed instructions below)

Automatic Slewing

Choose your target on the screen of the star chart or from the database

31

of extensive celestial objects in the menu and slew the telescope to your target. Enjoy your observing! (Detailed instructions below)

I. Locating the AXD Mount

After setting up the telescope, locate the AXD mount so that its R.A. axis points toward the north celestial pole if you use the telescope in the Northern hemisphere.

If your intention is not to take lengthy astrophotography, you don

’t need to align the R.A. axis to the celestial pole precisely. A rough setting will work well for visual observation. While looking for the polar star, locate the mount so that it faces toward the north and the elevation of the R.A. axis matches the latitude of your observing site.

-

Loosening the adjustment screw on one side will allow you to tighten the screw on the other side to change the altitude and azimuth directions.

-

If you use the telescope in the Southern hemisphere, locate the AXD mount so that the RA axis points toward the south celestial pole and set the elevation of the mount to be equal to the latitude of your observing site.

3. Loosen the R.A. and Declination lock clamps on the mount and position the telescope’s optical tube so that it points toward the west and is level. Refer to the image of the telescope displayed on the screen to understand it correctly. When you fix the position of the optical tube, tighten the R.A. and declination lock clamps on the mount. After this, do not touch the lock clamps until you finish your observing. The home position is the first positioning of your telescope to determine. Set the home position by measuring with your eye as close as possible.

Note: The telescope’s optical tube points toward the east and is level when you use the mount in the

32

southern hemisphere.

III. Alignment

2.

The star chart in SCOPE MODE appears on the screen. The concentric target circles in the center of the star chart indicate due west. (The target circles indicate due east in the southern hemisphere.)

The AXD mount starts tracking at the celestial rate from that point and now the Go-To slewing will accurately bring a target object in the finder scope

’s field of view. You need to proceed to star alignment to set the pointing accuracy of your telescope.

After this, CHART MODE and SCOPE MODE will switch over each time you press the ENTER key while the star chart is displayed on the screen. Its status is displayed at the upper left on the screen. Pressing the ENTER key in CHART MODE will ask you to proceed to the Go-To slewing.

33

What is Star Alignment?

The star alignment matches celestial coordinates of stars memorized as location information in the STAR

BOOK TEN with positions of stars that can actually be seen in the sky. The location information is identified with a star and this paring is called

“getting an alignment point”.

CHART MODE and SCOPE MODE can switch over each time you press the ENTER key.

What is SCOPE MODE? What is CHART MODE?

SCOPE MODE is linked with the movements of your telescope. The top and bottom of the screen are highlighted in red in SCOPE MODE

The dialog box appears to confirm if you are ready to slew the telescope to the target you selected.

Choose OK and press the ENTER key to start the Go-To slewing. At the same time, the target is marked and a position of the first alignment star is indicated on the bottom of the screen by its coordinate.

Chapter 4


Note:

If the “Go-To message” is set to off, the Go-To slewing will start at once without confirmation.

This chapter assumes that the

“Go-To message” is set to on.

The telescope starts moving toward the target.

(GOTO is indicated on the lower right of the screen.)

As soon as the Go-To slewing finishes, the STAR

BOOK TEN rings the chimes and the slewing speed is changed to the sidereal rate.

4.

Your first Go-To slewing may not bring the alignment star in the main telescope’s field of view but should appear in the finder scope.

Here, center Aldebaran in the telescope’s field of view as an example with the following procedure.

35

Move the telescope with the

↑

・

↓ direction keys so that you bring Aldebaran to the center of the finder scope

’s field of view. Magnifying the star chart with the zoom key will slow the motion of the telescope and thus allow you to make finer adjustments of the position.

B ring Aldebaran in the center of the finder scope’s field of view and look for it in the telescope’s field of view

Note:

Aldebaran will be away from the center of the target circles on the screen as you move the telescope to look for Aldebaran in the field of view of the telescope. This is caused by a difference between the actual position of Aldebaran viewed and the location of the same star in the database of the STAR BOOK

TEN. It is a normal behavior. In this stage of the star alignment, the telescope

’s field of view corresponds to a correct orientation of the telescope and disregard the position of the target on the screen.

After you place the target in the finder scope’s field of view, use an eyepiece with low magnification (A larger number eyepiece in millimeters such as a NLV20mm) to bring it in the field of view of the main telescope.

Then, change to an eyepiece with high magnification (A smaller number eyepiece in millimeters such as a

NLV5mm) so that you can center the target accurately.

Chapter 4


Slewing the Telescope to an Object near the Sun or to the Sun

If you try slewing to an object near the Sun or to the Sun, the STAR BOOK TEN will alert you with a dialog box:

“Warning! Target is close to the Sun.” In the dialog box, choose

OK with the

↑ or

↓

key and press the

ENTER key to advance.

CAUTION

When slewing to the object near the Sun, be careful not to have the Sun traverse the field of view of your telescope. Never look directly at the sun with your naked eyes or through the telescope. Permanent and irreversible eye damage may result. Make sure that the finder scope is covered with the objective cap.

36

Stop the Slewing Quickly

The movements of the telescope will pause if you press any of the keys (except the zoom keys) during the

Go-To slewing. Use this option stop the telescope quickly if the optical tube is about to hit something or if you want to cancel the ongoing slewing.

A t the same time, the dialog box appears to confirm to continue the Go-To slewing. Choose OK or Cancel with the

5.

Proceed to the second star alignment with a different star to increase the pointing accuracy of the telescope.

The more star alignments you have, the better your targets are centered. (You can perform a maximum 20 alignment points.)

Changing the Display Mode

Pressing the ENTER key a little longer will switch between CHART MODE and SCOPE MODE alternately.

In CHARTMODE, pressing the ENTER key a little longer will make the star chart screen key change to

SCOPE MODE and vice versa.

Tips on Star Alignment

-

It is advisable to use fixed stars for the alignments. As the distant stars are a fixed point of light and they have no area, you can pinpoint a location for an alignment point. Alignments with the moon, planets, nebulae and star cluster are not as accurate as star alignment with fixed stars.

-

Choosing several alignment stars which are separated over 10 degrees to other will increase the pointing accuracy of your Go-To slewing. Twenty points are available for the alignment.

-

The dialog box below appears if the selected star for the alignment is located within 10 degrees from the previously aligned stars.

If you choose OK , the aligned star less than

10 degrees apart will be deleted and replaced with the latest aligned star.

Choose Cancel if you stop the alignment.

-

The dialog box below appears if the star alignment is being done with the same star again. If you choose OK , the star alignment will be overwritten by new one.

Choose Cancel if you stop the alignment.

-

If the pointing accuracy of your telescope has not been improved, delete all the alignment stars and align the telescope from the beginning.

-

Using stars adjacent to the celestial poles for the star alignment may not contribute to improving the pointing accuracy of your telescope.

Chapter 4


-

Using stars near the horizon for the star alignment may result in disturbing the pointing accuracy of your telescope as it is affected by atmospheric conditions.

-

Choosing stars from the menu makes your star alignment more accurate than choosing stars from the star chart in CHART MODE.

-

If the target is not chosen, alignment will not work.

-

Each position of the aligned stars is defined by altitude and azimuth based on a point in time you aligned.

Every alignment star moves toward the west due to the diurnal motion. As a consequence, if the aligned stars moves more than 10 degrees (more than 40 minutes in time), the STAR BOOK TEN will accept the same star for alignment. This is a normal behavior.

38

- Calculations for star alignment are based on the most reliable two points among the alignment stars.

IV. Slewing to an Object in SCOPE MODE

Once the star alignment is completed in Section III, choose a celestial object to which you want to slew.

You can look for objects like nebulae and star clusters on the star charts of the STAR BOOK TEN to choose what you want to observe. Here, the Great Nebula, M42 in Orion, the Hunter is shown as a target.

II How to Use the Polar Axis Scope

What is Polar Axis Scope?

The polar axis scope is a small telescope that is installed parallel to the R.A. axis of an equatorial mount so that the polar axis scope can precisely point to the north (or south) celestial pole. Accurate polar alignment is essential for successful long exposure astrophotography of deep sky objects with the equatorial mount. Check longitude and latitude of your observing site with a GPS system or a map before the polar alignment. The polar axis scope allows you to accurately align the mount to Polaris at 3 arc minutes or less.

CAUTION:

- Inaccurate polar alignment could result in trailed stars and field rotation in your imaging device.

- It is not possible to use the AXD mount in the north latitude over 70 degrees and in the south latitude over

70 degrees.

Componets of the Polar Axis Scope

Polar Alignment in the Northern Hemisphere

1.

Set up the telescope on flat and hard ground where you can see Polaris in the sky. Point the polar axis of the AXD mount in the direction of north as shown in the figure. Adjust the tripod legs so that will the tripod is as level as possible.

2.

Take off the declination cap and polar axis cap. These caps can be removed readily by twisting counter-clockwise.

3.

Turn on the power switch of the mount and advance the initial settings until the telescope’s home position screen appears on the screen of the STAR BOOK TEN.

58

Chapter 5

APPLICATION

4.

While looking into the opening of the polar axis scope on the declination body, turn the declination body with the

↑ or

↓

direction key so that the objective lens of the polar axis scope can be seen in the opening.

5.

Adjust the mount in the altitude direction so that the indicator of the altitude scale fits the latitude of your observing site. The altitude adjustment screws are located on the front and rear sides of the mount base.

Loosening the screw on one side will allow tightening the screw on the other side to change the altitude.

The mount is set at an altitude of approximately 35 degrees at Vixen’s factory.

6.

While looking into the eyepiece of the polar axis scope, turn the focus ring until the reticle is in focus.

Hold the eyepiece tube with the other hand while you turn the focus ring.

7.

Adjust the brightness of the illuminator for the polar axis scope so that the reticle is dimly illuminated.

8.

Turn the time graduation circle by holding both sides of the bubble level so that the bubble is brought into the center of the level marks.

9.

Check the difference between the standard time meridian of your region (or country) and your observing site on a map of the area or by using a GPS system.

If the observing site is east of the standard time meridian, rotate the time-meridian offset scale in the direction as indicated by “E”. If the observing site is west of the standard time meridian, rotate the timemeridian offset scale in the direction as indicated by “W”. Turn the time-meridian offset scale while holding the eyepiece tube with the other hand.

Example 1:

If you observe in Okinawa Japan, which is located at 127 degrees longitude, you need to offset by 8 degrees in the direction of W from the central meridian of the Japan Standard Time after the calibration.

Example 2:

If you observe in Boston, MA, which is located at 71 degrees longitude, you need to offset by 4 degrees in the direction of E from the central meridian of the Eastern Standard Time after the calibration.

Example 3:

If you observe in Dallas, TX, which is located at 97 degrees longitude, you need to offset by 7 degrees in the direction of W from the central meridian of the Central Standard Time after the calibration.

Example 4:

If you observe in Los Angeles, which is located at 118 degrees longitude, you need to offset by 3 degrees in the direction of E from the central meridian of the Pacific Standard Time after the calibration.

10.

Match the date graduation circle with your local observing time by rotating the polar axis scope. The time graduation circle has a scale in 10-mimute increments, but you may set it as fine as two minutes.

11.

While looking into the eyepiece of the polar axis scope, turn the azimuth adjustment screws and the altitude adjustment screws alternately so that Polaris comes to the position in the reticle as shown in the figure. Readjust the brightness of the reticle to be dimmer if necessary.

Note: The position of the celestial poles moves gradually year after year due to precession. According to this, the position of Polaris shifts every year.

59

Chapter 5

APPLICATION

12.

Unfastening one side of the azimuth adjustment knobs will allow fastening the knob on the other side.

Loosen the Altitude adjustment bolt in the same way so that the mount body is moved slowly to high or low position in altitude.

Polar Alignment in the Southern Hemisphere

The polar axis scope contains a reticle showing the relative positions of four stars near the southern celestial pole. The stars are Sigma, Tau, Chi and Upsilon of the Octant. Polar align the mount with these four stars but precession is not considered.

1.

Set up the telescope in a flat and hard ground where you can see Octans, the Octant in the sky. Point the polar axis of the AXD mount in the direction of south. Adjust the tripod legs so that the tripod is as level as possible.

2.

Take off the declination cap and polar axis cap. These caps can be removed readily by twisting counter-clockwise.

3.

Turn on the power switch of the mount and advance the initial settings until the telescope’s home position screen appears on the screen of the STAR BOOK TEN.

4.

While looking into the opening of the polar axis scope on the declination body, turn the declination body with the

↑ or

↓

direction key so that the objective lens of the polar axis scope can be seen in the opening.

5.

Adjust the mount in the altitude direction so that the indicator of the altitude scale fits the latitude of your observing site. The altitude adjustment screws are located on the front and rear sides of the mount base.

Loosening the screw on one side will allow tightening the screw on the other side to change the altitude.

The mount is set at an altitude of approximately 35 degrees at Vixen’s factory.

6.

While looking into the eyepiece of the polar axis scope, turn the focus ring to have the reticle in focus.

Hold the eyepiece tube with the other hand when you turn the knurled focus ring.

7.

Adjust the brightness of the illuminator for the polar axis scope so that the reticle is dimly illuminated.

8.

While looking into the eyepiece of the polar axis scope, turn the azimuth adjustment screws and the altitude adjustment screw alternately so that the four stars of Octans comes into the field of view of the polar axis scope. Readjust the brightness of the reticle to be dimmer if necessary.

9.

While looking into the eyepiece of the polar axis scope, rotate the polar axis scope so that the four stars of Octans comes to the position in the reticle as shown in the figure.

60

Chapter 5

APPLICATION

Note: The position of the celestial poles moves gradually year after year due to precession. According to this, the pattern of Octans shifts every year.

Precise Polar Alignment

（

Drift Alignment

）

If you align the mount with the provided polar axis scope correctly, the mount will be able maintain tracking celestial obje cts within the field of view of your telescope’s eyepiece. For astrophotography, it enables you to take exposures of 5 to 10 minutes with a telephoto lens of 200mm focal length or less.

However, if you want to take longer exposures than 10 minutes or use a telephoto lens of longer focal length than 200mm, more precise polar alignment is required. The following method of polar adjustment will be done by watching the movement of a bright star in the eyepiece and it is called drift alignment.

CAUTION

Refrain from doing the star alignment with the STAR BOOK TEN if you need to perform the drift alignment.

If the mount type is chosen as “Equatorial mount without polar setting”, the position information collected by the star alignment will be applied for the polar alignment. This will spoil the drift alignment as any drifts from the celestial pole are detected and corrected automatically. Choose “Equatorial mount with polar setting” to avoid these corrections. Also turn off the function of depressing atmospheric refractions.

Drift Alignment in the Northern Hemisphere

1.

Align the mount to the north celestial pole by using the polar axis scope. This will save time during the process of drift alignment.

2.

Align the Mount in Azimuth

Prepare an eyepiece with illuminated reticle (cross hairs) or you use a Vixen OR12.5mm with illuminated reticle. Choose a bright star near the celestial equator and near the meridian, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see which direction the star moves. Confirm the west and rotate the eyepiece so that one of the cross hairs is parallel to the east-west direction in the field of view. The figure on the right shows the directions of north, south, east and west in the eyepiece according to a type of your telescope with or without a star diagonal.

The following descriptions are based on a telescope without a star diagonal.

Drive the mount at sidereal rate and look into the eyepiece to monitor the drift motion of the star in the north-south direction.

If the star drifts north (i.e. moves down due to inverted view), move the mount to east in azimuth.

If the star drifts south (i.e. moves up due to inverted view), move the mount to west in azimuth.

Adjust the mount with the azimuth adjustment screws. Make appropriate adjustments to the polar axis to eliminate the drift.

Align the mount to the south celestial pole by using the polar axis scope. It will save you a lot of time in the process of drift alignment.

2.

Align the Mount in Azimuth

Prepare an eyepiece with illuminated reticle (cross hairs) or you use a Vixen OR12.5mm with illuminated reticle. Choose a bright star near the celestial equator and near the meridian, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see which direction the star moves. Confirm the west and rotate the eyepiece so that one of the cross hairs is parallel to the east-west direction in the field of view. The figure on the right shows the directions of north, south, east and west in the eyepiece according to a type of your telescope with or without a star diagonal.


Drive the mount at sidereal rate and look into the eyepiece to monitor the drift motion of the star in the north-south direction.

If the star drifts south (i.e. moves down due to inverted view), move the mount to east in azimuth.

If the star drifts north (i.e. moves up due to inverted view), move the mount to west in azimuth.

Adjust the mount with the azimuth adjustment screws. Make appropriate adjustments to the polar axis to eliminate the drift.

3.

Align the Mount in Altitude

Prepare an eyepiece with illuminated reticle (cross hairs) or you use a Vixen OR12.5mm with illuminated reticle. Choose a bright star in east but not too low, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see in which direction the star moves. Confirm the west and rotate the eyepiece so that one of the cross hairs is parallel to the east-west direction in the field of view. The figure on the right shows the directions of north, south, east and west in the eyepiece according to a type of your telescope with or without a star diagonal.


Drive the mount at sidereal rate and look into the eyepiece to monitor a drift motion of the star in the north-south direction.

If the star drifts south (i.e. moves toward the lower left due to inverted view), move the mount to low in altitude.

If the star drifts north (i.e. moves toward the upper right to inverted view), move the mount to high in altitude.

Adjust the mount with the altitude adjustment screw ｓ

. Make appropriate adjustments to the polar axis to eliminate the drift.

Changing the Altitude setting of the AXD mount

The AXD mount is set for use in the middle latitude zone (latitude of 35 degrees plus/minus 15 degrees) at

Vixen’s factory. If your observing site is lower or higher than the range of the middle latitude zone, you need to change the current altitude setting to match the latitude of your observing site. The range of altitude adjustments is divided into three positions (low, middle and high) between 0 degrees and 70 degrees in latitude.

1.

Remove the optical tube and the counterweights from the mount.

2.

Remove the plain silver round cover on one side of the mount body where no altitude scale is engraved by unscrewing two setscrews with the 2mm Allen wrench.

3.

Loosen the bolt which is in the elongated hole as shown in the figure, with the 5mm Allen wrench.

Never take the bolt off.

4.

Loosen the center bolt with the 8mm Allen wrench while holding the mount head with the other hand so that the mount body is moved slowly to high or low position in altitude.

CAUTION Never tilt the mount body quickly. It may result in damage or lead to injury.

5.

Tighten the center bolt securely once you have reached the correct position.

6.

Put the silver round cover in place and tighten it with the two setscrews securely.

AutoGuider

The STAR BOOK TEN can be used for auto guiding in conjunction with a CCD video camera installed on a guide scope and a built-in autoguider (sold separately) as an extension unit for the STAR BOOK TEN. An external autoguider which is compatible with the ST series autoguiders from SBIG is available also. You can set up rate ｓ

for compensation to guide the telescope accurately.

The settings are defaulted to “RA: 10” and “DEC: 10”.

For an operation of the autoguider unit, please refer to instruction manuals provided by the autoguider or ask a manufacturer or a store of your autoguider.

～

What is Auto guiding?

～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

Auto guiding allows you to guide a telescope on an equatorial mount automatically by means of an autoguider, which compensates signals from a CCD video camera attached on a guide scope to achieve uniform and precise tracking speed of the equatorial mount. The advantages of the autoguider are most apparent during long-exposure astrophotography.

PEC (Periodic Error Correction)

～

What is PEC?

～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

Equatorial mounts with drive motors are designed to precisely track the motion of celestial objects. With the use of a telescope mounted on the equatorial mount, you may notice that stars in the field of view of the telescope at high magnification are drifting back and forth very slowly over a period of time (e.g. 320 seconds with AXD mount) in the direction of R.A. This is caused by the motion of the tracking gear wheels and it is part of the design of equatorial mounts.

The PEC (periodic error correction

1

) rectifies this phenomenon on the equatorial mount and records the correction electronically. Periodic errors of each AXD mount have been inspected and rectified to +/- 4 seconds periodic motion or less, and saved permanently on the AXD mount at Vixen’s factory, which is called V-PEC

2

. In addition, you can put your corrections on the mount for the better as the need arises

3

.

Note1: The PEC is saved and you can use the same correction from your last observing session.

85

Chapter 5

APPLICATION

Note2: Do not open the AXD casing or attempt tweaking the gears as the +/- 4 arc seconds of periodic errors are set by Vixen and altering them will void your warranty.

Note3: The tracking accuracy varies irregular motions and you need to correct them as precise as possible.

～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

Starting the PEC Recording

Backlash Compensation

Backlash is a momentary stoppage of the tracking motion of the mount that occurs when the motor gears reverse their rotation. Backlash does not occur while the mount moves at a constant speed as the gears keep contact with each other. Backlash may occur when the telescope is moved with the direction keys manually.

The backlash compensation provides a reduced time lag at the point of reversed motion where the gears lose the contact. It gives smoother rotation of the gears on the mount.

CAUTION:

Backlash compensation is not compatible with the PEC. Cancel using the PEC when you choose this option.

The settings are defaulted to “RA: 0” and “DEC: 0”.

Checking the Backlash

It is convenient to use a bright 1st-magnitude star in order to check a backlash amount for compensation.

1.

Precisely polar align the mount.

2.

In Scope Mode , choose the motor speed to be set approximately between 1.2x and 4.0x with the

↑ or

↓ zoom key with looking at the right corner of the information bar on the bottom of the screen.

3.

Confirm the amount of backlash in the direction of R.A as follows. Center the 1st-magnitude star in the filed of view of your eyepiece and watch how the star moves while pressing the

←

direction key. Press the direction key until the star begins to move.

4.

Press the

→

direction key to watch how the star moves in the field of view.

Chapter 5

APPLICATION

If there is a time lag and the star does not begin to move instantly toward the direction you press, a value for the backlash compensation is set too small (weak) or set to “0”.

On the contrary, if the star begins to move quickly and becomes larger at the same time you press, a value for the backlash compensation is set too large (strong).

5.

Confirm the amount of backlash in the direction of DEC in the same way with the

Pressing the ENTER key will shift the cursor to OK . Then press the ENTER again to save and leave the dialog box.

Note: Using the

↑ or

Tips on Setting of Backlash Compensation

Watch how the telescope moves when you increase the value. Start with setting an initial reference value

(10 for example), and double this value after checking the telescope movement with the initial value.

If the second value (=20) is too small to compensate for the backlash, enter the number doubled (=40) as the second value. Likewise, increase the number by doubling the value if necessary.

Example: Enter 20 for setting the backlash compensation.

If this value is too weak for the compensation, increase the value to 40. If it generates too much compensation as a result, decrease to the value halfway between 20 and 40. If the value of 30 is still somewhat larger for the compensation, decrease to 25. On the contrary, if 30 is somewhat small, increase to 35. In this way you can adjust the mount for the most effective backlash compensation.

Example: R.A = 10, DEC = 25

Motor Power

This allows for the changing electricity consumption of the mount as the need arises. When electricity consumption is set to “4”, the mount will easily accomplish tracking and GoTo slewing of your telescope and equipment up to 75 lbs (30 kg). The smaller the value is set, the lower the electricity consumption is used, but it may cause a failure in tracking or GoTo slewing due to a drop of the motor torques.

4 High : 7.5 watts to 27 watts

3 : 6.5 watts to 25 watts

2 : 6.0 watts to 22 watts

1 Low : 5.5 watts to 20 watts

Note1: Electricity consumption at the loading weight of 75 lbs (30 kg) would be about 7.5 watts to 30 watts.

The electricity consumption is affected by the size of equipment mounted and the temperature.

Note2: The wattages are based on the loading weight of 33 lbs (15 kg).

Chapter 5

APPLICATION

About Failure of Tracking or GoTo Slewing

If your telescope is not well-balanced or Motor Power is not set properly, the mount may not have torque enough to track or slew the telescope. If this happens, the STAR BOOK TEN will sound the alarm and the motors will stop momentarily. Then, the mount will restart the tracking and GoTo slewing automatically to reach the target. Although the mount retrieves its position information, it may spoil your astro-imaging due to the interrupted tracking.

If the alarm and stoppage of the motors occur frequently during your session, the dialog box will appear on the screen to tell you “Mount Motor Error”. At the same time the tracking (or GoTo slewing) will be stopped.

This alerts you the mount is n o longer able to keep the motion normal. Choose the “Motor Power” setting a step larger.

The mount still holds its position information but loses the target. To re-start the GoTo slewing you need to designate the target again. To re-start the track ing, access the “

Mount Setting

” menu and choose

Following Object .

Tips on Using the Motor Power Menu

If a total weight of the equipment installed on the mount is no more than 33 lbs (15 kg) (excluding counterweights) and well-balanced, the default set ting “3” would be sufficient enough to operate the mount stably. Chose the setting “4” if the loading weight exceeds 33 lbs (15 kg), and choose the setting “2” or “1” if the loading weight is far less than 33 lbs (15 kg) and you want to keep the electricity consumption as low as possible.

An allowable payload of the mount is limited according to the size of your telescope regardless of its weight.

Typically the larger the diameter of the telescope, the smaller the payload the mount accepts.

Do not overly restrain the electricity consumption as it may result in failure of the motor controls.

If you choose the setting “4” which generates the largest electricity and you still have a problem with momentarily stoppage of the motors, make sure of the following:

- Balance the telescope

- Try reducing the weight of the equipment installed on the mount

- Choose a slower GoTo speed.

- Check the power source. The AXD mount is designed to work at DC 12V. 2 Ah (ampere-hour) at the lowest. A power source of DC 12V. 3Ah and over is the recommended.

Equatorial without Polar Setting

-

Establishing star alignment in several points spread across the sky will make the GoTo slewing and tracking more accurate.

-

With the use of this option you can enjoy GoTo slewing easily without performing a polar alignment.

-

Since the mount is in motion without polar alignment, the tracking is done not only in the direction of R.A but also in the direction of DEC for correction. Choosing this option is not suitable for long exposure astro-photography.

Equatorial with Polar Setting

-

Since the mount is polar aligned, even a few points of star alignment will make the GoTo slewing very accurate. Adding points of the star alignment will make the GoTo slewing perfect.

-

The tracking at sidereal rate is made only in the direction of R.A and the motion in the direction of DEC is cut out. Because of this, the accuracy of the tracking depends on how the mount has been aligned to the north (or south) celestial pole correctly. If the polar alignment is inaccurate, your telescope will shift in the direction of DEC during the tracking.

Note: If the atmospheric reflection correction is in operation, it may affect the motion of RA and DEC

.

Cross Over Meridian

If your object of observation with the AXD mount is located on the east side of the meridian, the gravity of center of your telescope would be on the west side of the R.A axis of the mount. As the mount turns at sidereal rate tracking the object which moves toward the culmination, the optical tube approaches a place lower than the R.A axis of the mount. As a result, the optical tube may hit a leg of the tripod or the leg may interfere with instruments installed on the optical tube. To avoid this, the AXD mount has a safety function which makes the optical tube turn to the opposite position when the observing object comes to its culmination.

94

Chapter 5

APPLICATION

However, this may be troublesome if you intend to do astro-imaging of celestial objects in the south side of the sky or photographing an object that is almost approaching to the culmination during the exposure. The function of Cross Over Meridian allows you to change the timing of the reverse motion of the optical tube.

It is not possible to cancel the revised motion itself.

CAUTION

The function of Cross Over Meridian is a safety precaution to prevent the optical tube and equipped instruments from hitting the leg of the tripod. Wrong settings could cause scratches or damage to the optical tube and instruments, and could result in injuries. When using this function, be sure to check the configuration of each instrument installed.

The settings are defaulted to the following:
