Celestron EdgeHD 1400
In the matrix spot diagrams, note the tight cluster of rays in
green light, and the well balanced spherochromatism in the
blue and red. These spots are far better than spots from a fine
apochromatic refractor of the same aperture.
In green light, the EdgeHD 1400 is diffraction-limited over a
28mm image circle, although atmospheric seeing enables it
to display its full resolution only on the finest nights. Relative
illumination is 100% across the central 16mm, and falls
slowly to 83% in the extreme corners of a full-frame 35mm

image sensor. We have seen excellent results when the
14-inch EdgeHD is used with a KAF-16803 CCD camera over
a 50mm circle.
The EdgeHD 1400 is a massive telescope, well suited to
a backyard observatory or well-planned away-from-home
expeditions. Its long focal length and large image scale offer
skilled imagers the opportunity to make images not possible
with smaller, less capable telescopes.
