Celestron 6” Rowe-Ackermann Schmidt Astrograph (RASA 6)

RASA 6" Rowe-Ackermann Schmidt Astrograph: Ultra-Fast f/2.2 Telescope for Wide-Field Astrophotography

Lightning-Fast Imaging and Incredible Detail

Meet the RASA 6" (Rowe-Ackermann Schmidt Astrograph): a compact telescope designed to deliver breathtaking astrophotos with shorter exposures and observatory-class quality. Thanks to its ultra-bright f/2.2 optics, you capture more light in less time — perfect for astrophotographers seeking speed, portability, and pro-level performance.

Main Features

• ✅ Ultra-fast f/2.2 optics: reduces exposure time and often eliminates the need for autoguiding.
• ✅ Lightweight and portable: weighs just 8.4 lb (3.8 kg) with a versatile CG-5 dovetail.
• ✅ Sub-arcsecond resolution: ideal for high-resolution sensors and clear sky conditions.
• ✅ Expansive 3.8° field of view: perfect for galaxies, nebulae, and star clusters.
• ✅ StarBright XLT coatings: ensures maximum light transmission and high contrast.
• ✅ Built-in filter drawer and cooling fan: keeps performance high every session.

Compact but Powerful

The RASA 6 is built to provide exceptional image quality—whether under remote dark skies or in your home observatory. RASA technology is trusted in satellite tracking and space research, and is now available to advanced amateurs and passionate astrophotographers.

Shorter Exposures, Faster Results

With its f/2.2 focal ratio, the RASA 6 delivers sharp images even with very short exposures. Paired with a CMOS camera and live-stacking software, you can enjoy a near real-time astrophotography experience—perfect for efficient, productive imaging nights.
