Celestron has taken another bold step as the market leader in
telescopes with the introduction of their latest series of high-end
telescopes. Since the moment they first started producing Schmidt
Cassegrain optical systems, Celestron has continued to design
high-quality optics with pride. After years of research and development,
they have now taken one giant step! The Edge HD is
Celestron’s latest innovation that will surely be the system of choice
for the serious astro-imagers. The new Edge High Definition 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 HD
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
combined with our recently introduced CGX and CGEM-II mounts make the
new Celestron Edge 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. 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...
The Celestron CGEM-II mount has a fresh, attractive, bold appearance
and is capable of carrying Celestron’s higher-end SCT optical tubes (up
to 11") securely and vibration free which is ideal for both imaging and
visual observing.
Ergonomic Design - The Celestrom CGEM-II mount was designed to
be ergonomically friendly with large Altitude and Azimuth adjustment
knobs for quick and easy polar alignment adjustment. The internal RA and
DEC motor wiring provides a clean look and an easy and trouble free set
up.
Innovation - The Celestron CGEM-II series has a new innovative
Polar alignment procedure called All-Star (patent pending). All-Star
allows users to choose any bright star, while the software calculates
and assists with polar alignment. Another great feature of the CGEM
91526, sure to please astroimagers, is the Permanent Periodic Error
Correction (PEC) which will allow users to train out the worm gears
periodic errors, while the mount retains the PEC recordings.
Furthermore, a new dual saddle has resulted in this stellar mount having
the capacity to mount either CGE-Pro style Dovetails or CGE-5
Dovetails.
Performance - For objects near the Meridian (imaginary line
passing from North to South), the Celestron CGEM mount will track well
past the Meridian for uninterrupted imaging through the most ideal part
of the sky. The CGEM 91526 mount has a robust database with over 40,000
objects, 400 user defined programmable objects and enhanced information
on over 200 objects.
Celestron's CGEM-II mount is the perfect fit between the Advanced
Series and CGE Series. Offering the portability of the Advanced Series
and the precision of the CGE. Superior mount performance
combined with 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 HD 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.
