Thanks for that.
OK, so a sensor fast enough to read sequential images quickly, take many and reject the fuzzy ones, stack and process. I guess that's why webcams are popular.
But don't DSLRs have a sequential mode, say, 3 to 5 frames/sec, which might as well be used at higher ISO since inherent noise would be less of a problem with such a bright target? Or maybe movie mode (1080p)? Is either of those a good option for planetary imaging?
I don't presently own a DSLR .... so maybe that's an issue in that I don't fully understand their limitations.
