Please remember the field stop of the C6 is less than the usual SCT, so you will be limited to less than a degree (0.99) FOV no matter what diagonal and eyepieces you use.

I'm sorry to disagree with this statement. I can get at least 1.5° TFOV with my C6 and a 2" eyepiece (or with a 32mm 1.25" TV eyepiece and a f/6.3 focal reducer...even more). I was surprised to find this out on my own after so many people told me it couldn't be done. The 1.5° TFOV is a measured value using the drift method. I suspect there is some light drop off at the edge of the field of view, but I personally can't see it.

I highly recommend adding a 2" visual back to the C6 because it adds a lot more mechanical stability to the scope. It's alot easier holding up a pair of binoviewers with a 2" visual back compared to a 1.25" visual back.
