Once this is done, you are ready to attach other accessories, such as eyepieces, diagonal prisms, etc.
If you want to remove the visual back, rotate the slip ring counterclockwise until it is free of the rear cell.

The star diagonal is a prism that diverts the 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.
To attach the star diagonal onto the 8", 9.25" and 11" optical tubes:
1. Turn the set screw on the visual back until its tip no longer extends into (i.e., obstructs) the inner diameter of the
visual back.
2. Slide the chrome portion of the star diagonal into the visual back.
3. Tighten the set screw on the visual back to hold the star diagonal in place.

The 14" OTA comes with a 2" mirror diagonal that attaches directly onto the rear threads of the optical tube. See
figure 1-3.
If you wish to change the orientation of the star diagonal, loosen the set screw on the visual back until the star
diagonal rotates freely. Rotate the diagonal to the desired position and tighten the set screw.

The eyepiece, or ocular, is an optical element that magnifies the image focused by the telescope. The eyepiece fits
into either the visual back directly or the star diagonal. To install an eyepiece:
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.
