The tube offers a focal ratio of f/10 with the added versatility of Fastar (see below). You can also pair it with the f/6.3 focal reducer for even more astroimaging options. The Celestron C11-A can be mounted on a multitude of computerized telescope mounts thanks to its CGEM-style dov...
, with recent advances in image processing tools, I think the effect of this gets minimized - meaning, you can process things out rather easily. So, if you are trying to decide between CCD and CMOS, I think it will be OK to use CMOS with this particular scope at native focal length....
Factor in small pixel size of modern CMOS cameras with that long focal length and you get image scale - the size of the patch of sky that a single pixel will be exposed to. In a roundabout way you can think of this as an analog to magnification. That's not strictly accurate, but I...

Outfitted with an over-sized aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C11-A XLT 11" f/10 Schmidt-Cassegrain Telescope provides power and portability. The coating system consists of anti-reflection coatings on the corrector plate, hi...
1. This mount was never designed for unguided imaging. I wouldn't go unguided imaging with your 9.25 Edge or C11 on my Paramount MX+. It's a fools errand. 2. 18-arcseconds of error is fine if it guides well. My CGE had more, and guided to 1" RMS all day long. This mount isn...
I am primarily a visual observer. If that's you then go for the non Edge XLT. If its for Astrophotography then maybe the edge. I will say that you do get some thermals with the C11 given the size and the vents do help. Both EdgeHD and Non EdgeHD C14's now have vents, but the...
I own the Nexstar 8SE Optical tube, the C11 Optical tube and now own the Evolution 6 (Optical tube and mount)! I have been using the 6 and the 8 on this mount for EAA and planetary imaging. I plan on buying the Celestron Wedge in January and adapting a Polemaster to help with pola...
