Introducing the EdgeHD Telescope Series, Celestron’s new flagship
telescope line... fused to their CGX Mount, the newest and greatest in
German Equatorial mounts. With a proven telescope to mount atop it, the
CGX is sure to provide you with some of the finest astronomical
experiences you've had to date!
The EdgeHD is by now a well
proven and tested brand, with it's quality well assured by thousands of
satisfied customers.. and Celestron has chosen to pair it with their
amazing new CGX mount! This mount is years in the making, and is the
by-product of years of thought and planning on how to redesign the very
concept of a German Equatorial mount from the ground up and the top
down!
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 Edge 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 Celestron's recently introduced and
cutting edge CGX mounts make the new Celestron EdgeHD series the new
gold standard in Astro Imaging. The Edge HD 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. Once again, Celestron sets the benchmark!
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 CGX Mount is an innovative new design that improves on it's predesscors in every imaginable way.
Ergonomic Design - The Celestrom CGX mount is incredibly ergonomic, from the convenient carrying handles to the easy to use and turn knobs.
Splendid Engineering- This mount boasts drastically
reduced backlash and improved stability. Incredibly rigid, this mount
also boasts an improved motor system that greatly boosts the provided
torque. It's simply superior to it's predecessors in every way.
Innovation - The Celestron CGX series boasts internal cabling
that utterly bypasses the issue of cable twisting or tangling by letting
you route all your own power supply and accessory cables into a
convenient port on a part of the mount that moves- from which they enter
into the mount, utterly contained, and reach everywhere they need to on
the inside without any tangling issues. Neat and clean!
Performance - For objects near the Meridian (imaginary line
passing from North to South), the Celestron CGX mount will track a full
20 degrees past the Meridian for uninterrupted imaging through the most
ideal part of the sky. The CGX mount has a robust database with over
40,000 objects, utilizing a top quality Nexstar hand controller.
Celestron's bleeding edge new CGX mount is the current pinnacle of
German Equatorial Mount Engineering. Boasting a wide range of new and
improved features, this mount is simply top quality. It's just plain
better than it's competition and predecessors.
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.
