Friends from the European Union,the price you see is tax-inclusive, but
AliExpress does not directly charge tax for ordersover 150 euros,so when you
actually place an order, you will find that you only need to pay about80% of the

to pay US$1,000 (not including tax) when you buy it. IfFrench friendshave
problem that it needs to fill in theVATnumber, please contact the seller to
Other countries do not have these problems. thanks.

Celestron EdgeHD 8" OTA at a Glance
Mirror Support Knobs and Flexible Tension Clutches -hold the mirror in place and
reduce image shift when rotating the tube around the mount.
Tube Cooling Vents -located on the rear cell allow hot air to be released from
behind the primary mirror.
Fastar Versatility -All EdgeHD optical tubes are Fastar compatible for imaging
down to f/2 with optional accessories.
Brighter Star Images -Light becomes more concentrated when focused precisely.
This maximizes image brightness.
Dovetail Plate -for attaching to CGE mounts.
Sturdy Handle and Large Focusing Knobfor your ergonomic needs.
Special Features of the Celestron EdgeHD 8" OTA
True Astrograph Quality
EdgeHD optics produce a focal plane more than three-times flatter than a
standard Schmidt-Cassegrain telescope and dramatically flatter than competing
coma-free designs. This guarantees you visibly sharp stars across some of the
largest CCD chips available today.
Superior edge performance not only creates a rounder, more pleasing stars but
actually improves the resolution and limiting magnitude when compared to
telescopes of equal aperture. With Celestron’s StarBright XLT optical coatings
on every surface, EdgeHD optics gives you maximum light across the widest visual
and photographic spectrum.
In addition to EdgeHD’s optimized optical design, the telescope tube has been
redesigned to make sure you get the most from your optics each and every night.
Mirror Clutches -Flexible tension clutches hold the mirror in place and reduce
image shift when taking long-exposure astro-images. Once focused, the flexible
rods allow the mirror to be held in place without putting any force or pressure
on the mirror assembly, keeping the image centered in the eyepiece (or on the
Tube Vents- Cooling vents located on the rear cell allow hot air to be released
from behind the primary mirror. Each vent has an integrated 95-micron micromesh
filter guaranteed to let warm air out without letting dust in.
Fastar Versatility- All EdgeHD optical tubes are Fastar-compatible, allowing the
secondary mirror to be removed and replaced with a third party lens accessory
for ultra-fast f/2 wide-field imaging. Add the optional reducer
lens—custom-designed for your size EdgeHD tube—and you can increase your field
of view without sacrificing optical performance.
Every EdgeHD that ships have been tested not only for the surface quality of
each optical component but also with a camera and artificial star to ensure the
imaging system meets our rigid quality assurance. This “final acceptance test”
confirms the EdgeHD will perform in the field and deliver high-quality astro-images.
