Nice illustration Rob, stars look nicer in drizzled data for sure.
I'm wondering if purposely putting together a system that reasonably under-samples and then drizzling data is the ultimate solution for amateur astrophotographer.
As I understand it, at the same f-ratio (and same QE+read noise), undersampling system will be going deeper in the same time as opposed to a well-sampling system (say 2"pp at f/6 vs 1"pp at f/6), thus in the end one will have a higher SNR and a similar detail with undersampled and drizzled data comparing to a well-sampled data, given equal time of exposure. Or am I missing something here?
