Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the 8” RASA’s optics are designed to perform over a wider spectral range, from 400nm – 800nm. The lens group contains 4 elements and utilizes rare-earth elements. The design consists of a Schmidt corrector, primary mirror, lens group, and optical window. RASA’s optical design is patented (US 2016/0299331 A1).

The APS-C sized sensors used in many mirrorless cameras are a good choice. It is optimized for sensors with up to a 22mm diagonal, but performs well with sensors up to 32mm diagonal. The telescope 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. The key to the Ultra-Stable Focus System is a precision linear ball bearing, which is tested during assembly to ensure optimal results. Focusing is easier, more accurate, and more stable than ever. With the launch of the 8” RASA, Celestron is unveiled a focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. Weighing only 17 lb, this optical tube pairs perfectly with a wide variety of mounts. In many cases, autoguiding will not be required. The 8” RASA’s relatively short 400mm focal length also lessens equatorial tracking demands.

View images on a computer instantly that are brighter and more detailed than can be seen in much bigger telescopes with the naked eye.īecause shorter exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. When combined with sensitive cameras and the proper “live stacking” software, the 8” RASA can provide an almost real-time observing experience. Since it is an F/2.0 optical system, imagers can use shorter exposure times to capture detail in faint objects. Shorter Exposure Times and Virtual “Real-Time” Observing The prime focus focal plane is located at the front of the optical system, so it cannot accommodate a traditional eyepiece. Purely designed for imaging, the 8” RASA cannot be used visually. It has many of the same thoughtfully designed features as its “big brother” RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar. With the 8” RASA joining the lineup, a wider range of astroimagers can enjoy the benefits of the RASA design.

The latest addition to the RASA family, this 8” version is a much more portable and affordable version of the heralded RASA 11, which was introduced to much acclaim in 2014. It can capture stunning deep-sky astronomical images without the challenges typically presented by longer focal length instruments at a fraction of the cost of those systems. The 8” RASA is an imaging telescope that delivers a flat field without optical aberrations for razor sharp stars across a wide field of view.

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. Capture spectacular wide-field deep sky images in seconds with Celestron’s portable astrograph, the 8” Rowe-Ackermann Schmidt Astrograph (RASA).
