Is there ANY benefit to running flats for EACH filter, or does it not really matter? I was thinking perhaps any surface imperfections/motes could be more actively eliminated using filter specific flats.
Auto-performing 5hrs worth of darks now (600 sec and 1200 sec) and a run of bias frames (poofteenth of a minute total

), then deciding on flat run (still haven't finalised my lightbox, so will do perhaps T-Shirt ones tonight)
