The Celestron EdgeHD
15
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.
