About Celestron CGX-L 1100, 11" Rowe-Ackermann Schmidt Astrograph (RASA) Version 2

If you're an astronomy enthusiast or a professional astrophotographer, the CGX-L 1100, 11" Rowe-Ackermann Schmidt Astrograph (RASA) Equatorial Telescope - Version 2 is a high-quality, durable, and advanced piece of equipment designed to elevate your stargazing and imaging experience. This innovative telescope boasts a large 11-inch aperture, allowing for an influx of light that results in brighter, clearer, and more detailed images of celestial objects.

The sophisticated Rowe-Ackermann Schmidt optics system, coupled with a 4.48-inch eyepiece, provides a wide field of view, making it easier to locate and observe celestial bodies. This advanced-level imaging setup sets a new standard in astroimaging systems, producing images in a fraction of the time compared to other optical tubes.

The CGX-L mount is designed to provide superior performance for larger telescopes, taking full advantage of Celestron's most advanced technologies. These include All-Star Polar Alignment, Celestron PWI telescope control software, Starry Night Special Edition software, SkyAlign, and permanently programmable periodic error correction (PPEC).

The RASA V2 is the perfect companion to today's top DSLR or astronomical CCD cameras, offering a fast, wide-field f/2.2 system for shorter exposure times without sacrificing resolution. The short focal length lessens equatorial tracking demands, and in many cases, autoguiding will not be required.

The RASA 11 V2 features 4-element rare-earth glass optics for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range.

The RASA 11 V2 also utilizes the new Ultra-Stable Focus System (USFS), which minimizes focus shift and mirror flop. The integrated 12V DC MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.

Celestron's CGX-L computerized equatorial mount is the pinnacle of our fully computerized equatorial mount series. It is capable of carrying Celestron's largest optical tubes with ease, making it perfect for backyard observatories and remote imagers looking for exceptional load capacity to weight ratio, compact design, and innovative features that fully support large telescopes, imaging kits, and the latest in wireless tech accessories.

In conclusion, the CGX-L 1100, 11" Rowe-Ackermann Schmidt Astrograph (RASA) Equatorial Telescope - Version 2 is a sophisticated, high-quality, and advanced tool for any astronomy enthusiast or professional astrophotographer. Its innovative features and superior performance make it a standout choice in the field of astroimaging systems.
