Combine the exceptional wide-field imaging optics of the Celestron 11" f/2.22 Rowe-Ackermann Schmidt Astrograph (RASA) Version 2 with the proven excellence of the heavy-duty Celestron CGX-L go-to equatorial mount and you have an imaging scope that is equally at home in your backyard, in your observatory, or in the field at a dark sky site.

The Celestron CGEM II 1100 puts the big light gathering of 11" aperture Celestron Schmidt-Cassegrain optics on a newly-designed high precision go-to German equatorial mount for upscale performance that's surprisingly portable...

The Celestron CGEM II 1100 HD telescope combines big aperture 11" aplanatic EdgeHD high definition optics, a precision Celestron CGEM go-to German equatorial mount, and an ultra-premium 82° field Axiom eyepiece in a superlative and surprisingly portable true astrographic-quality telescope . . .

The Celestron CGEM II 800 combines industry-standard 8" Celestron Schmidt-Cassegrain optics with a newly-designed computerized go-to German equatorial mount for upscale performance at a price that won't break your budget . . .

• Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
• Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
• NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
• Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
• Performs over a wider spectral range than most telescopes, from 390 - 800 nm, so more of the light passing through the astrograph is in sharp focus.
• The CGEM II, with its 40 lbs load capacity, is the latest update to the venerable CGEM mount and provides a sturdy and rigid platform for the fully-loaded RASA 8.
• The drive system, consisting of low cog DC Servo motors with integrated optical encoders, steel worm gears supported by precision sealed bearings, and brass worm wheels, ensures smooth and accurate slewing and tracking.
• Proven NexStar+ computerized 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.

The Celestron CGEM II 800 EDGEHD telescope puts unique new 8" aplanatic(free from coma and corrected for spherical aberration)EdgeHD highdefinition Schmidt optics on a precision Celestron CGEM II  go-to German equatorial mount.... 

The Celestron CGEM II 925 combines high-contrast 9.25" Celestron Schmidt-Cassegrain optics with a newly-designed computerized go-to German equatorial mount for upscale performance that's a step ahead of an 8" scope, and at a price that won't break your budget . . .

The Celestron CGEMII  925 HD  combines 9.25" EdgeHD high definition optics with a precision Celestron CGEM go-to mount in an astrographic-quality telescope that any astronomer would be proud to call their own.

• Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
• Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
• NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
• Integrated air cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
• Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
• Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.
• The CGX, with its 55 lb. load capacity, is Celestron’s most innovative, state-of-the art, computerized equatorial mount to date, and provides a very sturdy and rigid platform for the fully-loaded RASA 8.
• The drive system utilizes 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+ computerized 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 Celestron CGX Equatorial 1100 HD Telescope is a large, yet portable, astronomer's dream. The EdgeHD optics excel at astro-photography giving you the edge you have been looking for.
