Typically for planets I use the Vixen NA140SF with Baader Fringekiller in front of the RGB filters and a mono USB camera - currently a ASI 178mm CMOS whic has 2.3um pixels.
Alternatively I have been recently trying to use the RC12.5" scope with the ASI 178 with colour filters and also a ASI 071 colour camera
On balance the 140mm refractor probably gets better views.
Cooke 152 mm refractor at Rossall School Observatory using Practica ML10 SLR on home-made camera mount. Eyepiece projection on Ilford FP4 @125ASA 1987, rest of details unknown.

Vixen VC200L on GP-DX/SS2K using ToUcam on x2.5 Powermate.( f/25 ). 90 seconds at 5 frames per sec with various gains. Note how even though taken with a slower webcam and a larger scope, its not as sharp or as well resolved as with the faster cmos camera with the smaller pixels on the smaller scope. Refractors win, unless you have a C9.25.
