Take 3fps and stack maybe 50-100 of those, nice image. You also get 12.8mp, so you'll be able to just resize, and get a lot less noticeable noise, with more detail.

There is no need to go for too many pixels in an image.. because then you just have too detailed image of your scope limitations.....
Toucam (640x480) format is optimal for prime focal and barlowed imaging of planets. And stacking the big number of captured frames reduces the camera noise and atmospheric turbulence. bringing out the capability of the mirror to its limits.
