A COMPLETE NO-NONSENSE ASTROIMAGING PACKAGE TO RIVAL ANYTHING AVAILABLE TODAY !

Capturing impressive deep-sky astroimages is easier than ever with Celestron’s new 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 better-looking astroimages in a fraction of the time, even without the use of an autoguider.The Rowe-Ackermann Schmidt Astrograph builds on the legacy of Celestron’s Schmidt Camera, the appearance of which made it possible for astrophotographers to produce images on film in the 1970s.

OPTICAL PERFORMANCE

Today, with CCD sensor sizes as large as film—or larger—the Schmidt Astrograph offers a full 70 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. 
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 that of a much more expensive instrument. The design also provides minimal vignetting.  Note: Photos above show the (L) new Rowe-Ackermann Schmidt design and the (R) classical Schmidt-Cassegrain design.

ADVANCED FEATURES

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. Meanwhile, a 12V MagLev fan reduces cool-down time and provides optimal air flow through the dust filtered optical tube. Engineered as a complete 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 fully-multicoated optical window or an optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.

PAIRED WITH CELESTRON’S CGEM DX MOUNT 

If you want to carry Celestron’s Rowe-Ackermann Schmidt Astrograph, you’ll need the serious stability of CGEM DX. This heavy-duty mount offers all the great features of our classic CGEM mount, with additional payload capacity and the ability to slew up to 50 lbs. at speeds of up to 5 degrees per second. The CGEM DX also offers extra large, 3-inch tripod legs for rigidity. With all that support, you can make the most of your Rowe-Ackermann Schmidt Astrograph for visual observing or astroimaging.
 

CELESTRON'S ROWE-ACKERMANN SCHMIDT ASTROGRAPH FEATURES:

  • 11-inch f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature
  • 70 mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging 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
