10. CONCLUSION The classic Schmidt-Cassegrain telescope introduced tens of thousands of observers and imagers to astronomy and nurtured their appreciation for the wonder of the night sky. Today, observers and imagers want a more capable telescope, a telescope that provides sharp close-ups as well as high-quality images all the way across a wide, flat field of view. But, consumers want this advanced optical technology at an affordable price. Celestron has designed the EdgeHD to meet customers' needs. The EdgeHD is not only coma-free, but it also provides a flat field so that stars are sharp to the very edge of the field of view. In this brief technical white paper, we have shown you the inner workings of our new design. We also demonstrated the care we exert as we build and test each EdgeHD telescope. We trust that we have proven that an EdgeHD is the right telescope for you. You may find the following resources to be useful in learning about optical design, fabrication, and testing: 11.
