  The Rowe-Ackermann Schmidt Astrograph, known mainly as the Celestron RASA, became one of the best astrophotography telescopes the moment it was released. Since then, its popularity has only grown due to the incredibly fast optics for efficient imaging, absurdly clear optics from edge to edge of the aperture, and the fact that it's one of the most reasonably priced, professional-grade telescopes available. Any astrophotographer will say the same great things about the Celestron RASA astrograph telescope. Experience as close to perfection as you can get in a portable package with the RASA series telescopes.

  Paired for Excellence with the Celestron CGX

  The Celestron RASA V2 11-inch has been paired with the CGX equatorial mount to bring out the best in your astrophotography system. With a load capacity of 55-pounds, you can fully customize your RASA to be the ultimate imaging rig. This mount is also fully-equipped with some of the best astrophotography software available, like StarSense and CPWI to bring professional-grade performance to an amateur-friendly system.

  Fast Optics for Short Exposures and "Real-Time" Observing

  Use shorter exposure times to capture detail in faint objects with its f/2.2 optical system. When combined with sensitive cameras and the proper live-stacking software, the 11-inch RASA V2 can provide an almost real-time observing experience. Instantlyview images on a computer that are brighter and more detailed than what you would see with the naked eye in bigger telescopes.

  Because shorter exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The 11-inch RASA's relatively short 400 mm focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.

  An Astrograph for Everyone

  The 11-inch RASA V2 is an imaging telescope that delivers a flat field without optical aberrations for razor-sharp stars across a wide field of view. It can capture stunning deep-sky astronomical images without the challenges typically presented by longer focal length instruments at a fraction of the cost.

  Focusing Made Easy

  Focusing is easier, more accurate, and more stable with the V2's electronic Celestron focuser, getting you that perfect focus with every use.

  Imaging in the Modern Age

  Designed to pair with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras, it is optimized for sensors with up to a 22 mm diagonal. It can accept larger sensors (up to 32 mm diagonal), as well as APS-C sized sensors used in many mirrorless cameras.

  Camera adapters, to connectC-mount cameras and cameras which mount withM42 threads are included.  

  Please note:The 11-inch RASA V2 will not work with standard DSLR + T-ring systems. OPT offers optional adapters to connect your 11-inch RASA V2 to Sony, Canon, or other mirrorless cameras.

  Unique Optical Design

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

  With many imaging systems, adding an extra piece of flat glass such as a filter does not change optical performance. However, that is not the case with super-fast optical systems like the RASA. The Celestron design engineers addressed this by designing the RASA with a removable optical window, so you can maintain peak optical performance if a filter is added or if a camera has its own optical window. Celestron offers a Light Pollution Imaging Filter designed specifically for the 11-inch RASA, which mounts in place of the optical window.

  All refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings. This maintains high light transmission through the entire optical system. When compared with Hyperstar SCT systems, the V2 RASA 11 provides better optical performance and field illumination.
