Autostacking using the drizzle algorithm?
Posted: Tue Oct 13, 2020 11:23 am
Hi Robin,
I am not quite sure whether this proposal makes sense but I'll try it ?
Especially since under UK skies the seeing is always the factor limiting resolution I am pushing more towards using 2x2 binning to gain sensitivity and to make the best of (e.g. Dob) short exposure times. However the price is to be heading towards undersampling ~(1.6-1.8 arc sec/ pixel).
So I wondered about stacking using the drizzle algorithm? Does it make sense (and is it even possible) to have this as an option for stacking within autostacks? Or would it then be difficult to further stack such drizzled autostacks (eg. in DSS) ? So it would be better to just collect lots of short conventional autostacks and then use the drizzle algorithm later in DSS?
best wishes
Tim
