Celestron C6-SGT Schmidt-Cassegrain.

Introducing the C6-SGT, the newest member of the Advanced Series family. Unparalleled
performance, unbeatable value!

The Advanced C6-SGT is Celestron’s first new Schmidt-Cassegrain optical system in over a
decade. A totally unique aperture size, the C6-S is available in computerized (GT) and non-
computerized models. Our NEW 6” Schmidt-Cassegrain features a precision optical system
with 1500mm focal length (f/10) and offers 40% more light gathering than a 5” telescope.

All C6-S models come standard with Celestron’s StarBright XLT coatings at no extra cost.

Mounted on the Advanced GT Series computerized mount, this telescope has some high
performance software and hardware features. Operated by our proven NexStar computer
control technology the telescope has a 40,000+ object database with 400 user-definable
objects and expanded information on over 200 objects. Custom database lists of all the most
famous deep-sky objects by name and catalog number; the most beautiful double, triple and
quadruple stars; variable star; solar systems; objects and asterisms.

Using the RS-232 communication port on the hand control, you can control the telescope via
a personal computer and our new flash upgradeable hand controls allow you to update your
telescope's operationg software via the internet. An autoguider port is also included for
astrophotography. No matter at what level you are starting out, this precision instrument will
satisfy your needs both visually and photographically.

CG-5 Mount - Precision engineered for stability.

Our new German Equatorial mount has precision worm gears on both axes for extremely
smooth stability. The key element that makes this system the most stable in its class is the
NEW heavy-duty tripod with larger and more substantial legs that offer excellent damping
characteristics for more stable views. The CG-5 also has a convenient latitude scale for
easier alignment and an optional polar finder scope for the ultimate in precision alignments.
