With the launch of the 8-inch RASA, Celestron is unveiling a new focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. This maintains high light transmission through the entire optical system and provides better optical performance and field illumination. All refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings. This allows more of the light emitted from the astronomical object to be sharply focused in the image. Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the optic is designed to perform over a wider spectral range, from 390-800nm. The lens group contains 4 elements and utilizes rare-earth elements. RASA’s optical design is patented (US 2016/0299331 A1) consisting of a Schmidt corrector, primary mirror, lens group, and optical window. Weighing only 17 lb, this optical tube pairs perfectly with a wide variety of mounts. In many cases, autoguiding will not be required. This astrograph is relatively short 400mm focal length and 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-inch 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-inch RASA cannot be used visually. It includes features such as the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar. With the 8-inch RASA, a wider range of astroimagers can enjoy the benefits of the RASA design. 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-inch 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-inch 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.
