Description

Celestron CGX-L 11 Inch Rowe-Ackermann Schmidt Astrograph

The Mount

The CGX-L is Celestron's highest capacity German Equatorial mount rated at 75lbs capacity- large enough for permanent installation in an observatory, yet remaining portable for use in non permanent locations. 144mm diameter worm wheels provide smooth operation and can more accurately drive heavier loads. A 270mm long saddle provides support to larger optical tubes. Remote operation friendly features such as home and limit optical sensors are standard equipment. In addition to that, mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and easier to transport.

The OTA

The Schmidt Cassegrain Telescope(SCT) is a hybrid optical design termed catadioptric. The modern SCT is a popular telescope design due to it's compact size vs aperture. StarBright XLT coated optics housed in a lightweight aluminum tube round out this popular design.
