Celestron 11" Rowe-Ackermann Schmidt Astro... $5,940.00
Capturing impressive deep-sky astroimages is easier than ever with Celestron's Rowe-Ackermann Schmidt Astrograph (RASA) V2, the perfect companion to today's top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won't need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required. Description RASA 11 V2 builds on the legacy of Celestron's Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure...

Celestron EdgeHD 11" Optical Tube Assembly... $5,940.00
EdgeHD 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. Description True Astrograph Quality Many 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...
