In that case, I'd recommend a C9.25 or C11 even more strongly
The difference I've experienced between using an 8" newtonian (fl 1000mm) Vs C9.25 (fl 2350mm) for planetary imaging is quite considerable, particularly when you add a 3x barlow or 4x powermate. I know the extra 1.25" of aperture does seem like it would be much of a difference, but it was.
A C11 would deliver an even greater advantage.
