WARNING
•Never look directly at the Sun with the naked eye or with a telescope
( unless you have the proper solar filter). Permanent and irreversible
eye damage may result.
•Never use your telescope to project an image of the Sun onto any surface. Internal heat
build-up can damage the telescope and any accessories attached to it.
•Never use an eyepiece solar filter or a Herschel Wedge. Internal heat build-up inside the telescope can cause these devices to crack or break, allowing unfiltered sunlight to pass through to the eye.
•Never leave the telescope unsupervised, either when children are present or with adults who may not be familiar with the correct operating procedures of your telescope.

ATTACHING VISUAL ACCESSORIES
INSTALLING THE FINDERSCOPE
Quantum telescopes come with a 9x50 finderscope. The specifications
for the finderscope refer to the magnification and aperture (in
millimeters). Therefore, a 9x50 finderscope magnifies objects nine times
and has a 50 mm objective lens.
INSTALLING THE STAR DIAGONAL
The star diagonal is a prism or mirror that diverts light at a right angle
to the light path of the telescope. This allows you to observe in positions
that are physically more comfortable than if you looked straight through.
FINDERSCOPE INSTALLATION
TO ATTACH THE 2” STAR DIAGONAL ONTO THE OPTICAL TUBE:
1. The finderscope comes attached to the dovetail finderscope bracket and is ready to be attached to the telescope.
1. Loosen the adapter ring set screws located on the end of the focuser.
2. Slide the 2” barrel end of the star diagonal into the focuser adapter ring.
3. Tighten the set screw on the adapter ring to hold the star diagonal in place.
2. Loosen the thumbscrew on the side of the dovetail mount.
3. Slide the base of the finderscope bracket into the
dovetail mount and lock down the thumbscrew to hold
in place.
If you wish to change the orientation of the star diagonal, loosen the
thumb screw on the focuser draw tube. This will allow the diagonal (or
camera for photography) to rotate freely. Rotate the diagonal to the
desired position and tighten the screw.
INSTALLING THE EYEPIECE
The eyepiece is an optical element that magnifies the image focused by
the telescope. To ensure that your telescope properly reaches focus, the
eyepiece should be inserted into the star diagonal. To install an eyepiece:
Dovetail
Mount
1. Loosen the set screw on the star diagonal until the tip no longer extends into the inner diameter of the eyepiece
end of the diagonal.
2. Slide the chrome portion of the eyepiece into the
star diagonal.
3. Tighten the set screw on the star diagonal to hold the
eyepiece in place.
To remove the eyepiece, loosen the set screw on the star diagonal and
slide the eyepiece out.
FIGURE 1-3
ALIGNING THE FINDERSCOPE
The finderscope is adjusted by using the six adjustment screws located
on the rings of the finderscope bracket. To make the alignment process
a little easier, you should perform this task in the daytime when it is
easier to locate objects in the telescope without the finderscope. To align the finderscope:
Focuser Draw
Tube Locking
Screw
1. Choose a visible object that is in excess of one mile away.
This will eliminate any possible parallax effect between the
telescope and the finderscope.
2. Point your telescope at the object you selected and center it
in the eyepiece of the telescope.

Adapter Ring
FIGURE 1-2
3. Check the finderscope to see where the object is located in the field of view.
4. Thread the knurled locking nut away from the finderscope bracket rings.
5. Adjust the thumb screws on the finder bracket until the cross hairs are centered on the target.
6. Thread the knurled locking nut down to hold the finderscope
securely in its bracket.

USING YOUR TELESCOPE FOR ASTROPHOTOGRAPHY
Quantum telescopes come with a thread-on field flattening lens design
to provide pinpoint images while imaging. To configure your Quantum
refractor for astrophotography:
1. Remove all visual accessories (eyepiece, diagonal) from
the focuser.
5. Now attach the M48 camera adapter onto the other end of the field flattener lens.
2. Unthread the focuser adapter ring from the end of the focuser (see image1-2).

3. Thread the photographic adapter ring onto the end of

4. Remove the caps from the field flattener lens and thread it onto the photographic adapter ring.

DSLR photography requires a model specific camera adapter for your model of camera. SkyWatcher makes a model for
Canon (S20300), Nikon (S20301) and Sony (S20302). Once
attached, your DSLR body (not included) will mount onto the
telescope just as it would attach to a camera lens.

Loosen the focuser retaining ring by rotating the entire ring
one-quarter turn counterclockwise. Use the small torque
handles to achieve a secure grip. Note: Do not remove the
focuser retaining ring or else the focuser will become
disengaged from the telescope tube.
2. Slowly rotate the entire focuser to the desired location.
3. Re-tighten the focuser retaining ring by rotating clockwise.

FRAMING YOUR CELESTIAL OBJECT FOR ASTROPHOTOGRAPHY
Quantum refractors give you two ways to rotate your camera for the
purposes of framing celestial objects on the camera chip.
FIGURE 1-6
As described above, your camera can be rotated by simply
loosening the thumb screw on the focuser draw tube (see Fig
1-1) and rotating the camera body to the desired position.
n
Focus Lock – On the bottom side of the focuser is a focus lock that
will disengage the focuser mechanism so that the position will not change
once the desired focus is achieved.
Additionally, you can rotate the entire focuser (with camera
attached) in order to frame your object. This method will ensure
that the camera body will always have the same orientation
relative to the focuser. To rotate the focuser:
n
In addition to the focus lock, there is a 2.5 mm set screw that can be
tightened in order to increase the tension on the focuser draw tube.This
can be tightened to reduce slippage when attaching heavy accessories
to the focuser. Remember to remove all accessories before making any
adjustments to the tensioning screw.

TELESCOPE MAINTENANCE
While your telescope requires little maintenance, there are a few things
to remember that will ensure your telescope performs at its best.
solution should be 60% isopropyl alcohol and 40% distilled water. Or,
liquid dish soap diluted with water (a couple of drops per one quart of
water) can be used.
CARE AND CLEANING OF THE OPTICS
Occasionally, you may experience dew build-up on the lens of your
telescope during an observing session. If you want to continue observing,
the dew must be removed, either with a hair dryer (on low setting) or by
pointing the telescope at the ground until the dew has evaporated.
Occasionally, dust and/or moisture may build up on the objective lens
of your telescope. Special care should be taken when cleaning any
instrument so as not to damage the optics.
If dust has built up on the lens, remove it with a brush (made of camel’s
hair) or with a can of pressurized air. Spray at an angle to the lens
for approximately two to four seconds. Next, use an optical cleaning
solution and white tissue paper to remove any remaining debris. Apply
the solution to the tissue and apply the tissue paper to the lens. Low
pressure strokes should go from the center of the corrector to the
outer portion. Do NOT rub in circles!
If moisture condenses on the inside of the lens, remove the accessories
from the rear cell of the telescope. Place the telescope in a dust-free
environment and point it down. This will remove the moisture from the
telescope tube.
To minimize the need to clean your telescope, replace all lens covers
once you have finished using it. Since the rear cell is NOT sealed, the
cover should be placed over the opening when not in use. This will
prevent contaminants from entering the optical tube.
You can use a commercially made lens cleaner or mix your own. A good
cleaning solution is isopropyl alcohol mixed with distilled water. The
