The wide field of view is perfect for capturing vast portions of the night sky, such as the busy Sagittarius constellation, the hydrogen-rich Cygnus region, the Orion Molecular Cloud Complex, and plenty more. In addition to this, the fast light gathering power and wide field of view is much less demanding on the telescope mount. In some cases, autoguiding may not even be required for sharp images!
Unrivaled Portability
The days of refractors dominating the grab and go title are no longer! The Celestron RASA 6 is redefining what can be achieved with a compact optical tube. Weighing in at a mere 8.4lbs, the RASA 6 weighs less than half that of the 8” model, while still providing sub arc second resolution, plenty light gathering power, and coma free color correct images. Refractors are no longer the only business in town! With a system this fast, packed into an OTA this light, you’ll be able to bring the scope under distant dark skies and capture stunning astrophotos with ease!
Innovative Control
Shaking up the amateur astrophotography scene takes more than just innovative optics, and Celestron is coming in stomping with the RASA 6! This cutting-edge telescope is ready to help you make the most of your time under the stars. With a fully integrated cooling system, the RASA 6 can adapt to ambient temperatures in no time at all. The interior 12V MagLev fan pulls air through two external mesh vents, rapidly bringing the OTA to equilibrium with the external environment while also ensuring the interior of your scope stays dust free. That means you won’t lose anytime waiting for your optics to cool! When used alongside the Celestron Celestron Smart DewHeater Controller 2x, or other compatible controllers, you’ll unlock to full power of this system, ensuring your optics are stabilized at their maximum efficiency all night long!
Effortless Camera Attachment
Rowe-Ackermann Schmidt Astrographs are designed solely for astrophotography, so it shouldn’t come as a surprise that the RASA 6 can deliver sub-arcsecond resolution. Providing a wide 3.8 ;° field of view and 16mm image circle optimized for 1” and 4/3 sized sensors, this telescope offers edge to edge sharpness, color correct and coma free imaging for numerous CMOS and CCD cameras. It can even support sensors up to 22 mm diagonal with minimal light loss. The RASA 6 also comes with an integrated 2” filter drawer that accepts both 1.25” and 2” filters, a clear optical filter designed to maintain peak performance when not imaging with other compatible optical filters, as well as a M42 T-thread camera adapter that will allow you to reach a desired back focal distance of 17.5 mm.
Please note: DSLRs are incompatible with the RASA 6, and camera bodies larger than 4” are not recommended as it will lead to decreased field illumination.
