Celestron 8" SCT and CGX computerised equatorial mount package
8" Schmidt-Cassegrain Optical Tube Assembly
Celestron's premium StarBright XLT coatings
Aluminium Optical Tube
2032 mm focal length (f/10)
The CGX, with its 55 lb. load capacity, is Celestron’s most innovative, state-of-the art, computerised equatorial mount to date, and provides a very sturdy and rigid platform.
The drive system utilises low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash.
Fully remote imaging capable, with optical limit switches, home sensors, through-mount cabling, and hard stops.
Included Celestron PWI software allows direct computer control via USB 2.0 connection.
Proven NexStar+ computerised telescope control technology supports functions to address imagers’ needs, such as All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.
This 8" aperture optical tube assembly (OTA) is the most popular size of Celestron's Schmidt-Cassegrain range. It features Celestron's StarBright XLT coatings on the corrector plate for maximum light transmission. The telescope has a 2032mm focal length (f/10) making it a good overall performer on a range of celestial objects.
The telescope comes with a star diagonal for more comfortable viewing of high altitude objects and a 25mm Plossl eyepiece which gives 81x magnification. A 6x30 finderscope to help locate objects completes the package.
The Celestron CGX Equatorial mount has been designed from the ground up to provide a solid and accurate platform for your telescope for both visual and astro-imaging requirements. The mount has a number of new and innovative features including a lower profile EQ head, which provides a more compact and stable mount; a better drive system; home and limit optical sensors with internal hard stops making it more remote operation-friendly; internal cable management.
In addition Celestron have made mechanical and ergonomic improvements too. These include conveniently located mount carrying handles to make transport and mounting (and removing) the mount on/off the tripod easier. There are also large latitude and dovetail clamp adjustment knobs to make the CGX easier to set up with your telescope.
The mount can be controlled with software developed in conjunction with PlaneWave Instruments - called CPWI - and is supplied free with the mount. CPWI uses advance PointXP mount modelling that allows you to add 100+ points to an alignment model for the mount set up, for the most accurate pointing and tracking possible for your Celestron telescope. The software also features an All-Star Polar Alignment routine, motor focus control and plate solving.
