Hmmm.

I know that F/3.3 is basically wasted money due to heavy vignetting, and my concern is that f/5 will be similar.

Apparently, f/6.3 is quite reasonable, even though there is still some vignetting, it can be somewhat mollified with the light box.

I guess this is my question. Has anyone had experience with this focal ratio on a 10" SCT, and what were the results like?

If someone has used this GSO 0.5x reducer on the same setup, then that would be even better. Fingers crossed.
