Celestron CGX 1100 RASA Computerized Telescope - V2

The CGX 11" RASA from Celestron sets a standard for affordable, advanced astroimaging equipment that will help you obtain those crisp, clear celestial images you've been striving for. The Rowe-Ackermann Schmidt Astrograph (RASA) is incredibly quick at producing images, working at a fraction of the time it takes for other OTAs. Coupled with the CGX mount, this telescope gives superior performance while utilizing many advanced technologies such as All-Star Alignment, Celestron PWI telescope control software, Starry Night Special Edition software, SkyAlign, and PPEC!

The Celestron RASA V2 (version 2) is a fast, wide-field f/2.2 system, meaning this set up allows for shorter exposure times when compared to traditional f/10 imaging. And it doesn't sacrifice resolution! With the shorter sub-exposure times, the advanced equatorial mount will not need to track over extended periods of times. This means that the time spent tracking has the potential of being more accurate.

For today's large CCD sensor sizes, the 1100 RASA V2 has a 43.3mm optimized image circle to capture pinpoint stars on even the largest of imaging chips. Even with huge sensors that have diagonals of up to 52mm wide, the optical performance is excellent. When looking at the image circle and the focal length of 620mm combined, you are looking at great performance for wide-field imaging!

Optical Performance

The RASA 11 V2 comes equipped with 4-element rare-earth glass to provide images free of false color and aberrations. Say goodbye to coma and field curvature! The design even lends to minimal vignetting. The optics are StarBright XLT coated.

1100 RASA Features

Ultra-Stable Focus System (USFS) : Celestron's USFS uses a precision linear ball bearing at its heart. The bearing minimizes focus shift and mirror flop. It's also compatible with Celestron's Focus Motor (not included).

12V DC MagLev Fan : This fan is integrated and reduces cool down time while providing optimal airflow through the dust filtered optical tube.

Camera Adapters : Celestron has made sure to include two adapters, the T-thread and M48 camera adapters, for easy attachment to popular CCD and DSLR cameras.

CGX Computerized German Equatorial Mount

The innovative and ergonomic look of the Celestron CGX mount is the culmination of years of GEM mount design by Celestron’s engineers. Always on the cutting edge of design, functionality and engineering, Celestron has achieved a new level of state-of-the-art with the CGX Series Equatorial Mount. The increased load capacity of 55 pounds will accommodate larger optical tube assemblies, and won’t blink an eye when you add a camera, autoguider with rings, focal reducer, filter wheel, and other imaging accessories that help you create amazing astro-images. This increased capacity and rigidity does not come at the expense of portability. The Celestron CGX EQ Mount only weighs 44 pounds, and the tripod weighs just 19.2 pounds.

The Celestron CGX has a lower profile than mounts that have come before it. Well-placed carry handles and ergonomic lock knobs make it easy to set up and make adjustments to the mount. a dual fix CGE/CG-5 dovetail saddle accepts your choice of OTA. The CGX is more responsive, with spring-loaded worm gears and belt drives that minimize backlash. Internal cabling keeps your RA and DEC cables out of the way, and the power and accessory ports that do accept cables in the traditional manner do not move with the mount. This feature, along with limit sensors and internal hard stops on both RA and Dec work to prevent cable wrap and tripod strike.

The Celestron CGX Equatorial Mount tracks 20-degrees past the meridian on either side to maximize the best imaging time. Technologies such as SkyPortal WiFi and StarSense AutoAlign are supported, and All Star Polar Alignment technology is built-in, for faster and easier polar alignment. New telescope control software for automation and remote operation has been designed for the Celestron CGX in conjunction with Planewave Instruments. This software features multi-point GoTo modeling, focusing and plate solving. With this innovative software, no third party advanced PC control software is needed!

The Celestron NexStar + hand controller is your interface with the CGX mount. It has a celestial database of 40,000 objects, and has fun features such as a automated tour of the best objects up on the date and time you are observing! The backlit buttons are intuitive and easy to use in the dark, and a new USB port on the end of the controller means you won't need an RS232-to-USB adapter.

The newly redesigned CGX tripod has a larger footprint for extra stability and comes with 2” diameter steel tripod legs that have graduated markings for quick leveling. The spreader bar/accessory tray adds extra stability to the heavy-duty tripod, and offers a few places to store your extra eyepieces, including your smartphone, when observing. This tray does not have to be removed before you can collapse your tripod for storage or transport. Finally, the head of the tripod is larger to accommodate the CGX mount, which has an adjustable base to place the center of gravity over the tripod when working at extreme latitudes.
