Meet the Celestron RASA 6, a compact astrograph designed to deliver spectacular astrophotography performance without sacrificing portability. As the smallest member of the Rowe-Ackermann Schmidt Astrograph (RASA) family, it combines advanced optical performance with a compact form factor, making it an excellent choice for imagers who want to take their setup wherever the night sky leads. Featuring an ultra-fast f/2.2 optical system, the RASA 6 is built for capturing detailed astroimages efficiently. Its fast optical design makes it well suited to astrophotographers looking for a powerful imaging platform that can perform both at remote dark-sky locations and in a backyard setup. Despite its compact size, the RASA 6 is designed to open up new possibilities for astrophotography. Whether you're traveling to remote locations in search of darker skies or expanding an existing home observatory, the RASA 6 provides a portable way to pursue high-performance deep-sky imaging.

RASA Performance for Everyone

For astrophotographers who demand speed, precision, and convenience in a compact package, the 6” RASA is the ultimate tool. Its f/2.2 design dramatically shortens exposure times, making it easier to capture crisp, detailed images of faint deep-sky objects without the heavy burden of extended tracking. Since RASA technology debuted in 2014, it has become the trusted choice for space surveillance and satellite tracking, relied upon by defense contractors, professional researchers, and governments alike. Like its bigger brothers, RASA 6 features a flat field for sharp stars from edge to edge. With RASA 6, you get the same technology trusted by the pros, but at a price that’s within reach for most, including those looking to add a second grab-and-go astrograph to their arsenal. RASA 6 defies the limitations of smaller and slower instruments. It collects more light and provides higher resolution than the refractors in its price range, allowing you to capture faint details in galaxies, nebulae, and star clusters in less time.

Features

  • Lightning-Fast Imaging: RASA’s legendary ultra-fast f/2.2 optics let you capture deep-sky images with briefer sub-exposures and less total exposure time —often eliminating the need for autoguiding.
  • Mobile But Mighty: Weighing just 8.4 lb and featuring a versatile CG-5 dovetail, the RASA 6 is ready to image wherever you are.
  • Sub-Arcsecond Potential: With advanced optics capable of sub-arcsecond resolution, RASA 6 perfectly pairs with a high-resolution camera and favorable sky conditions to reveal fine structures in galaxies and nebulae.
  • Expansive Field of View: Designed for sensors up to 22mm diagonal, RASA 6 offers a generous 3.8° view that effortlessly frames wide celestial targets.
  • Maximized Light Throughput: Celestron’s proprietary XLT coatings ensure every image bursts with brightness and contrast.
  • Convenience & Customization: With built-in features like a filter drawer and cooling fan—and optional upgrades—RASA 6 adapts to your evolving astroimaging needs.
  • Advanced VX Mount: The perfect platform for RASA 6, this capable and portable German equatorial mount delivers rock-solid stability, precise tracking, and robust support for payloads up to 30 lb.
