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 Celestron first started producing Schmidt Cassegrain optical systems, they have continued to design high-quality optics with pride. After years of research and development, they 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 Celestron 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 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 make the new Celestron EdgeHD series the new gold standard in Astro Imaging. The EdgeHD 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. Celestron 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... 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 EdgeHD 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.
