Celestron EdgeHD 800 Optical TubeCELESTRON EDGEHD 800 OPTICAL TUBE Celestron EdgeHD 8" is an Aplanatic Schmidt telescope designed to produce 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, but also to give an astrograph quality flat focal plane all the way to the edge of the field of view. Benefits: Visibly Sharper Images Coma-free, flat-field optics Enhanced Mechanical Features Fastar Compatible True Astrograph Quality Many optical designs that advertise themselves as "astrograph" quality actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for visual observing, stars will appear out of focus at the edge when used with a 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 other competing coma-free designs. This guarantees you visibly sharp stars...

Celestron RASA 8" OTACelestron 8" Rowe-Ackermann Astrograph (RASA 8) Please ask us about stock levels Capture spectacular wide-field deep sky images in seconds with Celestron s new portable astrograph, the 8 Rowe-Ackermann Schmidt Astrograph (RASA). This incredibly fast f/2.0 system is the perfect companion to today s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely. Weighing in at just 17 pounds, it s easy to transport your 8 RASA to the most remote dark sky locations. Key Features: Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor. 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 o...

Celestron 11" RASA OTA11" ROWE-ACKERMANN SCHMIDT ASTROGRAPH (RASA 11) V2 OPTICAL TUBE ASSEMBLY (CGE DOVETAIL) The NEW Celestron astrograph telescope features 11" f/2.2 Rowe-Ackermann Schmidt optics and rare-earth glass for images free from false colour, coma and field curvature. NEW upgraded v2 model with improved Ultra-Stable Focus System (USFS) to reduce focus shift and mirror flop. 52 mm imaging circle ensures pinpoint stars to the edges of the largest imaging sensors. Custom engineered linear brass focuser bearing reduces image shift and provides precise, smooth focussing. Built-in, quiet, high-output 12v MagLev fan to reduce cooldown time and block dust. Celestron s new Rowe-Ackermann Schmidt Astrograph, the perfect companion to today s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system offers two advantages over traditional f/10 astroimaging: better apparent tracking and shorter exposures. That means you ll create better-looking astroimages in a fraction of the time. Because s...
