Celestron 11" CGX-L Equatorial 1100
Rowe-Ackermann Schmidt Astrograph Telescope

Producing impressive deep-sky astroimages is easier than ever with Celestron’s new 11" CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system offers two huge advantages over traditional f/10 astroimaging: better apparent tracking and shorter exposures. That means you’ll create quality astroimages in a fraction of the time, without an autoguider.

With modern CCD sensor sizes as large as film, or larger, the 1100 Rowe-Ackermann Schmidt Astrograph from Celestron offers a 43.3 mm optimized image circle to capture pinpoint stars on the largest imaging chips. Combine this large image circle with a focal length of just 620 mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying new stellar fields, and even comet hunting.

The Rowe-Ackermann Schmidt Astrograph features newly designed optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle is unprecedented for an astrograph in this price range, or even for much more expensive instruments. This design also provides minimal vignetting.

Advanced features like a custom engineered linear brass focuser bearing and FeatherTouch Micro Focus Knob allow you to make the fine adjustments you need to capture the perfect shot. Incorporating a 12 V MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube. Engineered as an astroimaging system, every component of the Rowe-Ackermann Schmidt Astrograph is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or an optional imaging filter, every component of the Celestron 11" CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph Telescope was designed and fabricated to work together seamlessly.

Celestron's newly designed CGX-L Computerized Equatorial mount is the latest addition to their fully computerized equatorial mounts. Capable of carrying Celestron’s largest optical tubes with ease, CGX-L is designed 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.

Key design features are larger 144 mm diameter worm wheels which provide smoother operation and can more accurately drive heavier loads, a longer 270 mm dovetail saddle to support larger optical tubes, remote operation friendly features such as home and limit optical sensors, easier polar alignment adjustments, and better cable management. In addition the mount is sturdier, easier to use, and easier to transport.

Together as a system, the Celestron 11" Rowe-Ackermann Schmidt Astrograph (RASA) on their massive CGX-L EQ Mount provides an astronomer with an unsurpassed equipment setup for astroimaging. Whether you install this equipment package in your own home observatory, or transport it to a favorite dark-sky imaging site, or use it for remote observatory operation, this 11" Astrograph (RASA) on a CGX-L EQ Mount will become the heart of your dream imaging system for celestial wonders. Simply supply your favorite imaging camera/computer system, and you will be prepared to achieve amazing astroimaging results!
