Telescope-Astrographs-Celestron CGX 1100 RASA Computerized Telescope – V2

Fast Optics and Precise Tracking: The Celestron CGX 1100 RASA – V2!

Combining two of their most sought after innovations, Celestron introduces the CGX 1100 RASA Computerized Telescope – V2! The highly regarded 11” Rowe-Ackermann Schmidt Astrograph riding atop the heavy duty CGX Equatorial Mount is the ultimate system for seasoned astroimagers looking to take their astrophotography to the next level. As one of the largest telescopes in the series, this 11″ in aperture provides 1.9x the light gathering power of the 8″ RASA. Imaging at an incredibly fast focal ratio of f/2.2 is an astrophotographer’s dream, and the wide field of view lets you capture immense clouds of nebulosity in a single frame. This OTA is also equipped with premier glass for stunning images with zero coma and aberration. With quality like this, Celestron delivers an astrophotography experience that’s a cut above the rest!

An OTA of this caliber needs a just as impressive support system in place to maximize its abilities. This is why the Celestron CGX Equatorial Mount was the prime choice to pair with this 11” RASA. The belt driven system, robust worm gears, and spring loaded brass worm wheels provide smooth, seamless maneuvering across the night sky. Its high payload capacity easily carries this bulky, 43lb RASA, and allows the addition of a plethora of accessories! At the base of this mount is a sturdy and rigid stainless steel tripod for rock solid stability.

The Celestron RASA: An Optical Design Beyond Compare

Elevating the famed Schmidt Cassegrain Telescopes, Celestron has developed an optical system that takes astrophotography to the next level. The patented Rowe Ackermann Schmidt Astrograph features an incredibly fast native focal ratio of f/2.2, an outstanding advancement from the typical f/10 systems! Imaging at a lower focal ratio means much more signal is collected in less time for brighter, more detailed images without a sacrifice in resolution. For instance, an exposure time of 30 seconds with the RASA is equivalent in brightness to an exposure time of ~10 minutes with an f/10 SCT. That’s 20x as fast! In addition to this, the focal length of just 620mm produces a wider field of view, allowing you to capture vast regions of the night sky. This shorter focal length paired with the fast focal ratio is much less demanding on the telescope mount, and in many cases, autoguiding may not even be required for sharp images! Furthering the wide field imaging capabilities of this RASA, the large image circle of 43.3mm makes it compatible with the majority of camera sensors on the market today. Enjoy focused, pinpoint stars all the way to the corners of the frame. Even the largest camera chips with a diagonal of 52mm can benefit from this high performance optical design. Furnished with 4-element rare-earth glass, say goodbye to coma and field curvature! False color and aberration are eradicated while vignetting is significantly minimized. Celestron has also included their patented StarBright XLT coatings for maximum light transmission, enhancing performance even more.

Having systems in place to preserve image stability is crucial for the highest quality of astroimages possible. Understanding this, Celestron has assembled this 11” RASA with an internal focuser along with a built-in fan! This Ultra-Stable Focus System (USFS) possesses a precision linear ball bearing for reduced image shift while focusing. Not only this, but this focus design also reduces the effects of mirror flop, the unwanted primary mirror movement during different telescope pointing positions. The 12V DC MagLev fan helps this RASA quickly reach temperature equilibrium with its external surroundings and provides dust filtered airflow through the optical tube. For your convenience, a CGE dovetail is affixed to the top of this RASA 11 for easy attachment of a guidescope for enhanced tracking stability. These carefully engineered additions aid in delivering peak performance for images brimming with clarity!
