  • 11” f/2.2 Rowe-Ackermann Schmidt Astrograph (RASA) V2 uses rare-earth glass for images free of false color, coma, and field curvature
  • Heavy duty CGX computerized equatorial mount with 55-lb payload capacity

The CGX 11” RASA telescope is an excellent advanced-level imaging setup. The Rowe-Ackermann Schmidt Astrograph (RASA) produces images in a fraction of the time compared to other optical tubes. The CGX mount provides superior performance for larger telescopes while taking advantage of Celestron’s most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, Starry Night Special Edition software, SkyAlign, and permanently programmable periodic error correction (PPEC).

Rowe-Ackermann Schmidt Astrograph Features

This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. 

Optical Performance

The RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature.

Advanced Features

Engineered as a complete astroimaging system, every component of the RASA 11 V2 is optimized for peak performance with DSLR and astronomical CCD cameras.

CGX Mount

Capable of carrying the RASA 11 with ease, the CGX is perfect for backyard and remote imagers looking for exceptional load capacity to weight ratio, compact design, and innovative features that fully support advanced telescopes, imaging kits, and the latest in wireless tech accessories.

Solar Warning
  • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
