Home Telescopes Celestron Telescopes Celestron CGX Telescopes Celestron CGX Equatorial 800 HD Telescope
CGX 800 HD combines Celestron's all-new state of the art CGX computerized equatorial mount with its acclaimed EdgeHD optical system. With 8 inches of aperture and our premium StarBright XLT coatings, the CGX 800 HD gives you over 800 times the light gathering power than the unaided eye and is the lightest and most portable telescope in its class.
See the Universe in HDEdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view. True Astrograph QualityMany optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.Improved PerformanceSuperior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestrons StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.Mechanical FeaturesIn addition to EdgeHDs optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor). Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in. Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lenscustom-designed for your size EdgeHD tubeand you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.Included in this package 8" HD optics Celestrons premium StarBright XLT coatings provide maximum light transmission A 9x50 finderscope, 1.25" mirror diagonal for more comfortable viewing, and 1.25" 40 mm Plössl eyepiece are all included Celestrons premium StarBright XLT coatings provide maximum light transmissionCGX Equatorial Head CGX Tripod Accessory Tray One 17 lbs counterweight NexStar+ Hand Control DC Power Cable (plugs into cigarette lighter socket)HD FEATURES Experience our best optical performance with EdgeHDs ?at-?eld and coma-free optics for pinpoint stars all the way to the edge of todays largest imaging sensors and widest eyepieces Aluminum optical tube with tube vents featuring an integrated 95-micron mesh filter allows hot air to be released from behind the primary mirror.

This final acceptance test confirms the EdgeHD will perform in the field and deliver high-quality astroimages.CGX MountCelestrons engineering team have applied their years of experience designing German Equatorial mounts to the all-new CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use.The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits. Key design goals included a lower profile EQ head, which provides a more compact and therefore more stable setup; a better drive system; remote operation-friendly with home and limit optical sensors; easier polar alignment adjustments; and better cable management. In addition to that, weve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and transport. The CGX is our new Equatorial backbone to support a wide range of telescopes.Optical Design EdgeHDAperture (mm) 203.2 mm (8 in)Focal Length 2032 mm (80 in)Focal Ratio 10Focal Length of Eyepiece 1 (mm) 40 mm (1.57 in)Magnification of Eyepiece 1 51xFinderscope 9x50Star Diagonal 1.25Optical Tube AluminumHighest Useful Magnification 480xLowest Useful Magnification 29xLimiting Stellar Magnitude 14Resolution (Rayleigh) 0.69 arc secondsResolution (Dawes) 0.57 arc secondsLight Gathering Power (Compared to human eye) 843xSecondary Mirror Obstruction 2.7 in (69 mm)Secondary Mirror Obstruction by Diameter 34%Secondary Mirror Obstruction by Diameter 11%Optical Coatings StarBright XLTOptical Tube Length 17 in (432 mm)Optical Tube Weight 14 lbs (6.3 kg)Dovetail Compatibility CGE Mount Mount Mount German Equatorial MountInstrument load capacity 55lbsTripod height adjustment range 47.25 to 77.5 including EQ headATripod leg diameter 2"Latitude adjustment range 3º-65ºTripod Weight 19.2 lbsEQ Head Weight 44 lbsMax Slew Speed 5º/second (4º/second is default)Tracking Rates Sidereal, Solar and LunarNumber of Auxiliary ports (for hand control and accessories) 2Autoguide Port YesUSB Port YesSoftware New telescope control PC software
