Aaah, it's a USB-2 device, enough said. That will severely reduce the fps rate. The best bang-for-buck OSC planetary camera out there right now is either the just released ASI462MC ($499), older technology ASI224MC ($379), or at the bottom end is the ASI120MC-S ($239).
However, for planetary there is no benefit for running anything higher than 8 bit. There is a great explanation for that here, and increasing your framerate even a little bit will help more than capturing more noise.
