I have my Orion version of this 8" Classical Cassegrain for about a week now and I must say I am very impressed. I have had many telescopes come and gone in the past 30 plus years. These scopes ranged from Newtonian, Dob, SCT, APO refractor, and from 4" to 14" in sizes.
One morning at 4 a.m. PST I had the Explore Scientific 82 degree 6.7 mm eyepiece in for 358x magnification on the moon and the sharpness and contrast were unreal. There was no image breakdown at all and the contrast was just excellent the black was black and the white was white. I have never seen the moon so razor sharp and high contrast through any my previous telescopes.
I think the open tube design, the eleven light baffles, no front corrector plate, fixed primary mirror, Crayford style 2-speed focuser all contributed to great images.
The scope was slightly out of collimation when I received it and I re-collimated it using my Cheshire eyepiece. I did have to adjust both the secondary mirror and the primary mirror. Since the secondary mirror was center spotted so collimation was quick, easy and accurate. Orion did provided a peep hole kinda end cap for collimation but don't count on it. It was a joke. The peep hole wasn't even drilled center to the end cap and the small black donut ring tapped on the inside was also off center. Even doing the collimation a in bright room or outside you still couldn't quite see the black donut reflection so spend an extra $20 and buy yourself a Cheshire eyepiece.
One thing I still have to get use to is the fact that this is a fixed primary mirror design so focusing is done by moving the eyepiece in and out, Orion included one 2" extension ring and two 1" extension rings, and a 3" travel drawtube to deal with back focus requirement for all sort of eyepieces and equipment you may want to hang at the back. But that also produces a very long train at the back of the scope and makes the scope back end heavy. I have a used a clamp on 2.5 lb counter weight on the bottom D-style dovetail plate.
The Orion or GSO 6" and 8" CC or RC designs are basically the same structure with the differences are in primary mirror figure and focal ratio. I am a visual astronomer and I rarely do astro-imaging so I picked the CC with f/12 for a little better contrast visually vs. the f/8 RC.
All in all for $1000 you have a very portable, decent aperture, and very good optic telescope for lunar and planetary viewing. My two thumbs up.
