MrStarGuy,
AUTOMATIC SLEWING
Automatic Slewing
Start automatic slewing after you generally understand the basic operation of the telescope.
Automatic slewing allows your telescope to search for celestial objects based on the position of each object stored in the memory of the STARBOOK-S.
19
Flow of Automatic Slewing
Setting the Telescope To Home Position Move the telescope to the home position (initial position of the telescope). The telescope tube is leveled and orientated to point west (in the southern hemisphere, point the telescope tube east) using the STARBOOK-S.
Aligning the Telescope Select celestial objects from the STARBOOK-S database as reference points. The first slew from the home position can position the telescope in the vicinity of a target object. You will need to move the telescope so that its field of view matches that of the
STARBOOK-S screen.
Automatic Slewing Automatic slewing can begin after you complete a two-point alignment.
Home Position
After you finish setting up the telescope, turn the power switches of both the RA motor on the mount and STARBOOK-S hand controller to ON and complete all the initial settings. (Refer to pages 13 to 17.) The screen will display the text shown on the right.
Inc.
focus on a distant object before proceeding.
Note: If you have advanced to CHART MODE or SCOPE MODE, turn off the STARBOOK-S and restart to reach the above mentioned screen again.
(1)Slew the telescope by pressing each of the keys on the STARBOOK-S to confirm that the telescope tube moves in the same direction as the corresponding image of the sky.
(2)Position the telescope tube so that it is level and pointing toward the west in the northern hemisphere (east in the southern hemisphere) as shown in the figure.
MrStarGuy,
20
Align the Telescope
(1) After moving the telescope to the home position, pressing the Select key will display the western sky on screen in the northern hemisphere (the eastern sky in the southern hemisphere).
Tracking at sidereal rate starts at this time, but you should align the telescope to make the tracking more accurate.
Inc.
From among the celestial objects stored in the memory of the STARBOOK-S, at least two objects must be selected as reference points to allow accurate automatic slewing and precise tracking of celestial objects. Choose well-known bright stars to use as reference objects. Repeat this procedure on at least two stars.
(2) SCOPE MODE and CHART MODE are alternated each time the Chart or GOTO key is pressed.
The current MODE status is shown at the upper left of the screen. In SCOPEMODE, both the screen and telescope move simultaneously with the keys. In CHART MODE, only the screen is scrolled with the corresponding image of the sky. Always use CHART MODE when searching for celestial objects on the screen. The two modes are linked to each other but
MrStarGuy,
21
What is SCOPE MODE?
In SCOPE MODE, as you slew the telescope, the star chart on the screen moves along with the telescope as its direction changes. SCOPE MODE is displayed as soon as you begin automatic slewing after a GOTO command. Use this mode when you want to fine tune the pointing of the telescope.
(3) SCOPE MODE appears on screen after initialization when the power on the STARBOOK-S is turned on. Change it to CHART MODE by pressing the Chart key. CHART should now appear at the upper left of the screen as shown below.
Center the celestial object that you wish to use as a reference point on the screen with the
Inc.
Reference objects may also be selected from the Object Menu (see page 40).
Hint 2 The zoom+ key enlarges the star chart on the screen. In CHART MODE it allows you to scroll the chart slowly in a small area enlarged so that you can center a reference object on screen more accurately. In SCOPE MODE it allows you to point the telescope more precisely.
The Zoom- key reduces the star chart on the screen. It allows you to scroll the screen quickly over a large area. The motor speed / zoom level indicator is visible at the lower left of the screen.
Hint 3 When you center a reference object, which is shown on the screen, in the field of view of your eyepiece, try to center it as precisely as possible. This will increase the accuracy of the system.
MrStarGuy,
What is CHART MODE?
Unlike SCOPE MODE, the telescope is not linked to the screen in CHART MODE. Search for objects in CHART MODE before starting automatic slewing. You may also use this mode when you simply wish to refer to a star chart.
22
(4) Center the celestial object you wish to use as a reference point in the circle on the screen.
Example: Center the chart on Arcturus in the constellation Bootes (the herdsman).
(5) When the Zoom+ key is pressed once, the star chart is zoomed in by one step. It enables you to make finer adjustments.
(6) With each press of the Zoom+ key the star chart is zoomed in more.
Inc.
(7) Enlarge the star chart until the outer of the two concentric circles goes off the screen. Refer to
Hint 4.
(8) Move Arcturus to the center of the circle and press the GOTO key. MrStarGuy,
Hint 4
You may not be able to center a reference star exactly in the center of the circle, but it is ok if it is slightly off center.
Automatic slewing begins.
23
Caution The telescope moves quickly when automatic slewing starts. Pay attention to its range of motion. The telescope stops immediately when any of the STARBOOK-S keys is pressed during automatic slewing. Press any key to stop in emergency. To restart automatic slewing, reselect a reference point to align the telescope.
(9) A beep indicates the completion of automatic slewing. Make sure that the telescope has stopped its movement and the screen on the STARBOOK-S has changed to SCOPE MODE.
Center Arcturus in the field of view of the telescope’s finder scope and then point the telescope so that Arcturus is in the center of the field of view of the telescope’s eyepiece by pressing the
keys. Refer to Hint 5 & Hint 6.
* Arcturus may move off the center on the screen as you move the telescope, but disregard this.
Hint 5 The Zoom+ and Zoom- keys are linked with the speed of the telescope. Zoom in on the star chart with the Zoom+ key when you want to move the telescope slowly, and zoom it out with the Zoom- key when you want to move the telescope quickly.
Hint 6 With a high power eyepiece, move the reference star into the exact center of the field of view. Careful use of the Zoom+ and Zoom- keys will enable you to make comfortable fine adjustments.
(11) Press the Align key on the STARBOOK-S after centering the reference star Arcturus in the field of view of the telescope. MrStarGuy,
* If “Confirm GOTO” (see page 33) is selected, a dialog box will pop up to let you confirm the alignment. Choose YES and press Select to enter.
24
(12) A one point alignment is completed. The reference star Arcturus comes to the center of the target on the screen of SCOPE MODE.
Press the Chart key and change the screen to CHART MODE to make the second and additional
Refer to Hint 7 to Hint 13.
Inc.
Hint 7 Zoom the star chart out with the Zoom- key to find the next reference object over a large area of the sky.
Hint 8 The alignment system is designed to improve pointing accuracy by setting two reference points as a pair alignment. Choosing a second reference point within 90 degrees in azimuth of the first will increase the pointing accuracy in the same area of the sky. However, choosing reference points within 10 degrees of each other will be warned with a beep and you will need to select reference points separated by greater than 10 degrees to perform the alignment correctly.
Hint 9 In a pair of reference points for alignment (= a pair alignment), two reference points that
MrStarGuy,
Hint 10 If you wish to use reference points that are more than 90 degrees apart, first make a pair alignment with reference points that are located within 90 degrees of each other. Then make a second pair alignment in the same way, but the third reference point can be more than 90 degrees from a former (second) reference point. Pair alignments made across the whole sky will keep the pointing accuracy high in every direction.
25
Hint 11 Choosing a reference point near the zenith will make pointing accuracy worse. Due to the nature of equatorial mounts, you won’t be able to improve the pointing accuracy near the zenith even if you complete a pair alignment perfectly. Use a low power eyepiece to search for a celestial object in this case.
Hint 12 A variety of celestial objects can be used for reference points; the Moon, planets, nebulae and star clusters. However, using a reference star (fixed star) is recommendable as it may be difficult to determine the center of extended celestial objects like nebulae or star clusters.
Hint 13 Up to 19 alignment points may be used to raise slewing accuracy.
Starting Automatic Slewing
Automatic slewing becomes available as soon as a two point alignment (the first pair alignment) is that you are interested in observing one by one. Refer to Hint 7 to Hint 13.
Inc.
The following is an example for slewing to the planetary nebulaM57 (the Ring Nebula) in the constellation Lyra (the Lyre).
(1) Zoom the star chart out on the screen by pressing the Zoom- key to find the target constellation in a large area of the sky.
(2) In CHART MODE, locate your target (hereafter M57) in Lyra with the keys.
MrStarGuy,
(3) Zoom the star chart in (along the way) by pressing the Zoom+ key to center M57 on the crosshairs with the keys.
26
(4) Continue zooming in further while centering M57 in the crosshairs with the keys.
(5) Press the GOTO key.
(6) As soon as the GOTO key is pressed, CHART MODE changes to SCOPE MODE and the telescope starts automatic slewing.

(3) The Messier catalog is displayed. Only those objects above the horizon will be shown. Move the cursor to the target object (M27 here) with the keys and press Select to enter.
(4) Some brief data of this celestial object (M27) is displayed. Choose OK and press Select to enter.
MrStarGuy,
If you decide you wish to select a different object, choose Cancel instead to go back to the Messier catalog.
(5) When the GOTO key is pressed, the telescope starts moving to point to the target object
(M27).
28
Note 1: The STARBOOK-S Object Menu list will display only those celestial objects which are in the sky above the horizon at the current time and location.
Note 2: The object label may appear twice next to the selected object.
Note 3: The Object Menu also includes the Sun, Moon, planets, constellations, NGC/IC objects and well-known celestial objects. You can search for them in the same way.
Warning!
Inc.
Never look directly at the sun with your naked eyes or through the telescope without the proper filter attached. Permanent and irreversible eye damage may result. Do not leave the telescope unattended while it is pointed at the sun. It may cause a fire.

Backlash Compensation
Backlash is a momentary stoppage in the movement of the telescope due to a sluggish engagement of the gears. It occurs when the direction of the movement is reversed. The backlash does not occur while the telescope moves at constant tracking speed.
The backlash compensation can adjust time lag when the direction of the telescope movement is
MrStarGuy,
Checking the backlash compensation
To verify the amount of backlash compensation, it is easiest to use a bright planet, star of the first magnitude or the Moon.
(1) Polar align the mount exactly so as to point the R.A. axis of the mount to the North Pole of the sky.
(2) Change the screen to SCOPE MODE, and down the speed of the telescope to the slowest or the second slowest with the Zoom+ key.
36
(3) Center your target celestial object in the field of view of the telescope, and then press the RA+ key to verify how the object moves in the field of view.
*It may not move immediately as you press the RA+ key. Continue pressing the key until it starts moving.
(4) Press the R.A.- key to verify how it moves in the field of view.
If there is a time delay before the object start moving when you press the key, it indicates that the amount of backlash compensation in the R.A. is too small. On the contrary, if the object moves in the R.A. is too large.
Inc.
(5) Next, press the DEC+ key and press the DEC- key in turn to verify how the object moves in the field of view.
Setting the backlash compensation
(1) Press Menu to display the System Menu on the screen. Move the cursor to Backlash
Compensation with the keys and press Select to enter.
(2) The default values for backlash compensation are set to 0 both in R.A. and DEC.. Move the cursor with the keys and select your setting preference with the Value+, Value- keys. MrStarGuy,
The values can be set between 0 and 100 both in R.A and DEC..
(3) Choose OK and press Select to enter.
Save the settings in order for the current settings to apply the next time the STARBOOK-S is used.

Tips on setting values of backlash compensation
Watch how the telescope moves when you increase the values. 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) 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 strong compensation as a result, decrease to the value halfway between 20 and 40. If the value of 30 is still somewhat large 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.

moving back and forth very slowly over a period of time (e.g. 10 minutes for GP2 and GPD2).
This is a result of viewing them at very high magnification. It is unavoidable since the equatorial mount is driven via gear wheels. However, it may be annoying when you are observing at high magnification.
The PEC (periodic error correction) function electrically rectifies this phenomenon in the equatorial mount. You can correct a drifting motion of the equatorial mount with manual operation of the buttons on the controller and memorize it in the STARBOOK-S. It will enable you to make more precise tracking by using the recorded motion*.
* The tracking accuracy relies on how you correct irregular motions. The tracking may deteriorate if the correction is made inaccurately.
Start the PEC recoding
(1) Position a guide star you want to use for the PEC recording in the center cross hairs of your guiding eyepiece. (You can use a Vixen GA-4 illuminated guiding adapter or a Vixen Or-12.5mm with illuminated reticle as a guiding eyepiece.) Use an eyepiece which yields a magnification of approximately 200 power.

On starting the recording the screen is automatically zoomed to the maximum. You can zoom down for the wide screen with the ZOOM – key, but be sure to set the zoom level at the maximum when you make the correction. Corrections may be useless in other zoom levels.
During the PEC recording, the guide star may begin slipping out in the direction of the tracking
(in the direction of RA). Use the RA+, RA- keys to keep the guider star at the center of the cross hairs.
When you start recording, the count starts at 600 (PEC: 600) and will count down. The
STARBOOK-S beeps intermittently for 10 seconds just before the completion of the recoding in
