The Rowe-Ackermann Schmidt Astrograph Design

The Rowe-Ackermann design pairs speed with performance.  Based on the original Schmidt camera design, the RASA optical tube offers major advantages to astro-photographers by giving you a short focal length for relatively a large aperture.  The result is a wide-field f/2.2 system offering the advantage of better apparent tracking.  With only a 620mm focal length, exposure times are also greatly reduced when compared to traditional Schmidt Cassegrain telescopes.   You'll be capturing better images in a fraction the time, without the need of an autoguider!

As CCD imaging has advanced, large sensors have become readily available in increasingly more affordable cameras.  While the imaging hobby has grown in leaps and bounds there has been very little changed in optical designs to accommodate these large imaging sensors.  That is until now.  The Celestron RASA offers an exceptionally sharp 70mm image circle.  This creates such a wide field, you'll be able to fill even the largest imaging chips with edge to edge pin point stars with minimal vignetting. The Rowe-Ackermann scopes are perfect for creating giant night sky mosaics, surveying and comet hunting.  Designed with 4-element rare-earth glass, images are free of false color, coma and field curvature.  Optical quality this excellent has been unheard of in astrographs within this price range.

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, a12V MagLev fan reduces cooldown time and provides optimal airflow 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 included fully-multicoated optical window or an optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.

Includes M48 and T-Thread camera adapters.

Celestron CGE Pro Computerized Equatorial Mount

The CGE Pro computerized telescope and mount series is Celestron’s newest line of observatory-class German equatorially mounted telescopes geared towards astrophotography. Long favored by astronomy buffs and astrophotograpers, the German Equatorial mount is a time-honored choice for its stability and portability - more stable because the center of gravity is directly over the center of the base and more portable because it can be broken down into smaller components for easy storage and transportation. For astrophotography, the German Equatorial mount offers easier balancing, unlimited space at the rear of the telescope tube to mount a camera, and whole sky access. Now you can enjoy all of the most sought after Celestron NexStar software and database features combined with the high standards and unflinchng tradition of the German Equatorial mount. Just take a look at what the Celestron CGE Pro Mount has to offer...

Payload Capacity - The CGE Pro equatorial mount has the highest payload capacity of all Celestron mounts. The mount can handle up to 90lbs in telescope equipment. The payload capacity is defined by Celestron’s engineering department as the load that is carried by the mount’s dovetail clamp. The payload capacity does not include the counterweights. For example, a CGE Pro 1400 has a 47-lb optical tube assembly. This weight is carried by the clamp. However, a CGE Pro mount has a payload capacity of 90 lbs. So it still has capacity for an additional 43 lbs in accessories, guidescopes, focusers, cameras, etc.

Tracking - The hallmark of any telescope mount is its ability to find, center and track celestial objects with the highest degree of accuracy. With larger .75" pitch diameter worm, precision made cut-steel gears in gearboxes, and seven slot skewed armature motors the CGE Pro delivers typical tracking performance of +-9 arc seconds, which can be further reduced with the mounts permanent periodic error correction (PPEC). Extended tracking pass the Meridian of up to 20 degrees of uninterrupted imaging through the best part of the sky.

Portability – Set up and transportation of the Celestron CGE Pro Mount is made easy by separating the mount into smaller, easy-to-carry components. Unlike fork arm mounted telescopes, the CGE’s optical tube can be quickly removed from its mount and can be easily assembled in minutes.

Stability – Recognized for superior stability, German Equatorial mounts place the center of gravity directly over the tripod legs and can be easily polar aligned without the use of an optional equatorial wedge. This proven design reduces the “tuning fork” vibration that can be associated with undersized fork mounts. An improved Super HD Tripod supports the Celestron CGE Pro mount. This fully extendable tripod is made from the finest 2.75” stainless steel and can be raised to a height of 55”. The tripod uses a dual leg support for maximum rigidity with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension.

Balance – The Celestron CGE Pro Mount can easily be balanced in both axes. Simply sliding the counterweight for Right Ascension and moving the optical tube along its dovetail mounting for Declinationaccomplishes balancing the weight of camera equipment and other visual accessories. This means that no additional weight needs to be added to balance the telescope when additional accessories are added.

Clearance – The Celestron CGE Pro mount supports the tubes at a single contact point allowing the tube to move freely around its polar axis without making contact with the telescope’s mount. Software features allow the user to set the mounts slew limits to guaranty safe motion. This is particularly useful when adding photographic and CCD instruments that extend from the rear of the telescopes.

Flexibility - The CGE Pro Mount is compatible with Celestron’s CN-16 GPS accessory. Combine the GPS and built-in real time clock and these telescopes will keep track and remember their exact location and time without having to enter the information into the hand control. With a maximum payload of 90 lbs. the CGE Pro mount is able to hold the telescope more securely even when fully loaded with all your imaging gear. Improved gearing and motors provide faster slew speeds than ever before with a maximum slew rate of over 5°/per second.

Alignment - No-Tool polar alignment with larger hand knobs for both Altitude and Azimuth adjustments are only where it begins with the Celestron CGE Pro Mount. Thanks to technological advancements in the All-Star software, all you have to do is choose any bright alignment star for a software assisted alignment of the mounts polar axis that will have you ready for imaging even if you can't see the North Star.
