Orion CT80 Instruction Manual

Orion
Congratulations on your purchase of an Orion CT80 Compact
Refractor! Your telescope has been designed with portability and
versatility in mind. Outfit it with your favorite accessories and pop
it on the mount or tripod of your choice and you'll be ready for a
superb observing experience. NOTE: If you are purchasing this
optical tube for use in the Awesome AutoGuider Package,
you'll need to perform some disassembly in order to fit the
tube into the rings. See below for detailed instructions.
The CT80 Compact Refractor comes fully assembled and optical-
ly collimated from the factory. The telescope's optics have been
precisely collimated at the factory, so they should not require any
adjustments. Please keep the original shipping box. In the unlikely
event that you need to ship the telescope back to Orion for warran-
ty repair service, you should use the original packaging.
WARNING: Never look directly at the Sun through
your telescope—even for an instant—without a
professionally made solar filter that completely
covers the front of the instrument, or permanent eye
damage could result. Young children should use this
telescope only with adult supervision.

Awesome Autoguider Package, the finder scope bracket must be
removed from the optical tube. The tube will not fit through the rings
otherwise.
Follow these steps to complete this procedure:
1. Locate and remove the three Focuser Assembly Screws to
remove the focuser (Figure 2). Be sure not to let the focuser
fall out of the tube when the screws are removed.
2. Carefully remove the focuser along with the silver trim ring
from the tube (Figure 3).
3. Locate the two Philips head screws in the finder scope base
(Figure 4). There are two nuts on the inside of the tube under
