Celestron CGE pro EdgeHD 11 inch
Introducing the EdgeHD Telescope Series, Celestron’s new flagship telescope line...
Celestron has taken another bold step as the market leader in telescopes with the introduction of their latest series of high-end telescopes. Since the moment Celestron first started producing Schmidt Cassegrain optical systems, they have continued to design high-quality optics with pride. After years of research and development, Celestron have now taken one giant step!
The EdgeHD is Celestron’s latest innovation that will surely be the system of choice for the serious astro-imagers. The new Edge High Definition telescope series features an Aplanatic Schmidt optical system that produces pinpoint star images all the way to the edge of the field. Some optical systems currently on the market may produce coma free images. But there is a difference.... the optical difference. Not only is the Celestron EdgeHD coma free, but it also has a built in field flattener to ensure sharp focus all the way to the edge of the field, producing true Astrograph quality images. This results in pinpoint, High Definition star images throughout your astro photograph.
These superior features combined with the recently introduced CGE Pro and CGEM mounts make Celestron's new Celestron HD series the new gold standard in Astro Imaging. The Edge is an aplanatic Schmidt telescope designed to produce aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma, but also to give an astrograph quality flat focal plane all the way to the edge of the field of view.
Many optical designs that advertise themselves as “astrograph” quality actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for visual observing, stars will appear out of focus at the edge when used with a flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt Cassegrain telescope and dramatically flatter than other competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.
Now let's talk about Celestron quality...
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...
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.
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.
Superior mount performance combined with superior edge performance not only creates rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. When it comes to the Celestron HD series coupled with Celestron’s StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum... It's a vision you'll never forget.
