![]() Weighing in at just 17 pounds, it’s easy to transport your 8” RASA to the most remote dark sky locations. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely. This incredibly fast f/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Simply add a mirrorless camera and this package offers everything you need to take spectacular images of wide-field deep sky objects.Ĭapture spectacular wide-field deep sky images in seconds with Celestron’s portable astrograph, the 8” Rowe-Ackermann Schmidt Astrograph (RASA). This kit combines the 8” Rowe-Ackermann Schmidt Astrograph (RASA) with the strong-yet-portable Advanced VX (AVX) German equatorial mount. Accessories included: M42 camera adapter, C-thread camera adapter, and fan battery pack.Also compatible with Vixen format dovetails longer than 100mm, but not compatible with Losmandy D format plates. Dual saddle plate is compatible with narrow CG-5 dovetails and wider CGE dovetail.This mount offers every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more.Advanced VX, the most compact and portable of Celestron’s German equatorial mounts, offers a maximum instrument capacity of 30 lb with the same rigidity as our larger mounts and minimal flexure.Performs over a wider spectral range than most telescopes, from 400-800 nm, so more of the light passing through the astrograph is in sharp focus.Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.Integrated air-cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust. ![]() Ultra-Stable Focus System – precision linear ball bearing virtually eliminates image shift.The astrograph does not work with standard DSLR cameras. 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.Rowe-Ackermann Schmidt Optical Design – 8” f/2.2 flat field imaging system with rare-earth glass for outstanding images free of optical defects like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
