Celestron strikes again with the high priced EdgeHD 800 CGEM
Schmidt-Cassegrain Telescope, in the same family as the previous scope
but costing a bit less by comparison. This 8 inch aperture telescope
does not hide the fact that it uses the same Schmidt-Cassegrain
technology as the last product, without a loss in detail or quality.
You’ll get the same flat focal plane that is necessary for accurate
The same goes for the EdgeHD’s coma-free cassegrain optics with the
built in flattener that not only gives you a better picture, but keeps
things professional without you having to mess around with the settings.
Aberration free images are the norm for this scope no matter how far
out into the galaxy you peek. Even telescopes that have the same
aperture of the EdgeHD 800 can’t produce images that are as sharp, due
to the quality of optics between the two. Even without counting in
natural light, there is a huge difference in the amount of detail you
will see on any given night with this product.
And like all EdgeHD models, if you move around a lot the adjustment
settings are a lot more forgiving. This includes a mirror lock so that
you don’t have to spend precious minutes readjusting the built in mirror
on every move you make. Product weight is a good stable 110 pounds
including the mount, so it will take a really strong gust to knock it
off of the base. Getting started you can align it using the stars, and
for the customers that become more advanced, polat aligning brings you
into the realm of what is necessary for astrophotography. For the
serious buyer that wants to save a little money, this could be the
perfect scope for their adventures, and worth a second or third look.
The first product on the list is far from cheap, and is the ultra-expensive Celestron EdgeHD 14 inch Schmidt Cassegrain Optical Tube Assembly
with StarBright XLT Coatings. This is a telescope loaded with features
from top to bottom, and is available in several styles like 11 inch
EdgeHD CGE, 14 inch EdgeHD CGE, 8 inch EdgeHD CG5, 8 inch EdgeHD CGE and
the 9.25 inch EdgeHD CGE. They all have a lot of features but are not
lacking in the power necessary for astrophotography, even on the
smallest version. This gives a lot of flexibility to a buyer that wants
this scope but doesn’t want to pay the premium price for the top tier
Concentrating on the 14 inch CGE version, it has a 14 aperture made
of aplanatic Schmidt-Cassegrain that is perfect for producing quality
astrophotography details. Besides the crisp images it provides the
coma-free optics work together with the field flattener so that you get
long, deep distance but a flat focal plane. This is the best combination
of settings you will find prebuilt into a telescope that is made for
astrophotography. If you have a habit of moving a lot then the stability
of this product will be perfect as it includes a flexible tensions
clutch so that the mirror does not get knocked out of place.
It gives a perfect mix of movement and sharpening of an angle all in
one package, and all without you having to be a perfectionist with the
settings. A known problem with certain telescopes is how the air can
sometimes mess with the optics, leading to many taking great care to
plan around using telescopes outside that use mirrors in their setup.
Because this telescope has cooling vents on the rear, hot air can be
released and bypass the mirror. This means not fogging up or distorted
image when you are ready to look through the telescope. With optional
accessories all version of the EdgeHD optical tubes are Fastar
compatible for imaging, right down to f/2. Not many on the list can make
this claim, and it is the prime reason why this is a top 5 choice on
the list, if not the very best.
