About Celestron CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph RASA Telescope

Explore the cosmos with unparalleled clarity using the Celestron CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph RASA Telescope, a high-quality instrument designed for the serious astronomer and astrophotographer. This sophisticated and durable telescope is a testament to Celestron's legacy of innovative astronomical equipment, offering advanced features for capturing breathtaking deep-sky images.

The Rowe-Ackermann Schmidt Astrograph boasts a large 11-inch (280mm) aperture, providing an expansive light-gathering capability to produce brighter, more detailed observations of the night sky. Its fast, wide-field f/2.2 optical system is a game-changer, offering two significant advantages over traditional f/10 systems: superior apparent tracking and the ability to achieve stunning astroimages with shorter exposure times. This means you can create exquisite celestial photographs quickly and efficiently, without the necessity of an autoguider.

Celestron's cutting-edge optical design includes a 4-element lens group made of rare-earth glass, ensuring images are free from chromatic aberration and common distortions like coma and field curvature. The optimized 43.3mm image circle is perfect for capturing pinpoint stars across the largest imaging sensors, making it ideal for wide-field imaging, creating vast mosaics of the night sky, surveying, and comet hunting.

The Rowe-Ackermann Schmidt Astrograph's optical performance is further enhanced by minimal vignetting and a focal length of just 620mm. The custom-engineered linear brass focuser bearing, coupled with the FeatherTouch Micro Focus Knob, provides the precision required for capturing the perfect shot. A 12V MagLev fan ensures rapid cooldown and maintains optimal airflow, equipped with a dust filter to preserve the integrity of the optical path.

The CGX-L mount, a cornerstone of Celestron's computerized equatorial mount series, supports the astrograph with exceptional load capacity, compact design, and user-friendly features. It is engineered for both backyard observatories and remote imagers, boasting larger 144mm diameter worm wheels for smooth operation and precise control of heavier loads. The extended 270mm dovetail saddle accommodates larger optical tubes, while integrated home and limit optical sensors, improved polar alignment adjustments, and enhanced cable management make for a seamless user experience.

Mechanical and ergonomic improvements throughout the mount ensure it is sturdy, intuitive to use, and easy to transport, making it the ideal companion for the advanced Celestron astrograph. Whether you're capturing the intricate details of distant galaxies or surveying the night sky, the Celestron CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph RASA Telescope is engineered to deliver superior performance for discerning astronomers and astrophotographers.

Celestron CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph RASA Telescope Features

  • Ultra-fast, 11-inch f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature. Cuts imaging time by more than half
  • Expansive 43.3 optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52 mm for larger format sensors.
  • Custom engineered linear brass focuser bearing reduces image shift, while dual-speed 10:1 FeatherTouch Micro Focus Knob provides the most precise focusing
  • Quiet, high-output 12V MagLev fan reduces cooldown time and blocks dust
  • Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras
