July 15, 2009 Announcing the EdgeHD Telescope Series! Celestron’s New Aplanatic Schmidt Telescope
Celestron has taken another bold step as the market leader in telescopes with the introduction of our latest series of high-end telescopes. Since the moment we first started producing Schmidt Cassegrain optical systems, we have continued to design high-quality optics with pride. After years of research and development, we have now taken one giant step!
• Visibly Sharper Images • Superior Performance • Enhanced Mechanical Features • Fastar® Compatible
The EdgeHD is Celestron’s latest innovation that will surely be the system of choice for the serious astro-imagers. The new EdgeHD 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 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.
Mechanical Features. In addition to Celestron’s new optimized optical design, the EdgeHD tube has been redesigned to make sure you get the most from your optics each and every night.
Mirror Clutches Flexible tension clutches hold the mirror in place and reduce image shift when rotating the tube around the mount. The flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or chip).
Tube Vents Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.
Fastar Versatility The EdgeHD is the most versatile imaging scope available today. At its native f/10 you can achieve the image scale necessary to capture the smallest of deep sky objects. With the optional reducer lens (coming soon) you can increase your field of view without sacrificing optical performance. A barlow gives you the added power for high resolution planetary, lunar and solar imaging. And of course all EdgeHD optical tubes are Fastar® compatible for ultra fast f/2 wide field imaging. Each tube has been fitted with a removable secondary mirror and are opto-mechanically aligned on a laser bench to ensure they are axially symmetric in any configuration.
