C14. The slighly slower focal ratio (f/11 vs f/10 for most other SCTs) keeps the central obstrucion in MCT territory and I believe makes the field a bit flatter.
I also believe that the field illumination (due to the big central baffle) is the best of all of the Celestron SCTs. The field seems uniformly bright when used with even the widest low power eyepieces (though of course the field is not very big)
The aperture makes is go deep enough that to get a noticable improvement you have to go to a 17" or 18" Dob and stand or sit on a ladder a lot.
See above.. VERY confortable to use.
Does is all. Best planetary scope I have ever owned, and deep sky close the the best 14" dobs around.
No other SCT I have owned has come close. Seems MORE than 3" bigger than the C11 in terms of all around performance.
