backing off the cable about 1/4" from being fully engaged. This method helps ensure there is no slippage when

You are now ready to put the telescope optical tube (5) onto the equatorial mount
(18).
1.
Slightly loosen the screws (4) that hold the mounting rings on the telescope in
place.
2. Slide the rings apart so that each is at the same distance as the holes in the
mounting platform (20).
3.
Place the telescope tube on the mount so that the treaded post at the bottom
of the tube rings go through the holes on the mounting platform.
4.
Thread a wing nut onto the end of the threaded posts and tighten to secure the
tube to the mount.
5.
Tighten the screws (4) that hold the mounting rings in place. This will keep the telescope from sliding back
and forth in the mounting rings.
Your telescope comes with the following optical accessories:
•
20mm eyepiece 1¼"
•
4mm eyepiece 1¼ "
•
3x Barlow Lens 1¼"
1.
Remove the caps from the focuser draw tube (3).
2.
Place the chrome barrel end of the eyepiece into the focuser (see Figure 1-4). Lock it into place with the
thumb screw on the side of the focuser.
3.
Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece (see
Magnification section of the manual). To use the barlow lens, insert the barlow lens directly into the
focuser. Then start by using the low power eyepiece such as the 20mm, and insert it directly into the barlow
lens.
1.
Remove the two small, silver thumbscrews located on top of the
telescope tube. See Figure 1-4.
2.
Place the finderscope bracket over the two holes in the telescope tube,
lining up the holes on the finderscope bracket with those in the
telescope tube.
3.
Insert the thumbscrews through the finderscope bracket and thread
them into the telescope tube.
