Maksutov-Cassegrain
Welcome to a new world of adventure! Your new
180mm Maksutov-Cassegrain (Mak-Cass) tele-
scope is a fine-quality instrument that excels for
high-power observing and solar system imaging.
These instructions will help you set up and properly
use and care for your telescope. Please read them

Please keep the original shipping box. In the unlikely event you
should need to ship the telescope back to Orion for warranty
repair service, you should use the original packaging. The box
also makes a very good container for storing the telescope.
The Orion 180mm Maksutov-Cassegrain has been upgraded to
now include a 2" visual back with 1.25" adapter (Figure 1),
allowing use of either 2" or 1.25" diagonals, eyepieces, and
accessories (all sold separately). In addition, the 2" visual back
can be removed to expose an SCT-threaded collar (2" x 24)
TPI. This would accommodate SCT-specific accessories such
as a thread-on diagonal or various camera adapters.
The 180mm Maksutov-Cassegrain comes equipped with
a Vixen-style dovetail mounting plate for attachment of the
optical tube to a compatible telescope mount. In addition,
the optical tube is outfitted with a dovetail finder scope base,
which accepts any Orion finder scope or reflex sight.
