Is there a script for post processing dark frame subtraction in general? (not only in meteor.lua)
(I'm sorry for the programmer of that script but I have found out meteor.lua and meteor2.lua are totally useless because my CANON POWERSHOT SX500 IS won't even save dark frames on the SD card. Loading a simple intervalometer script with RAW file saving option on, putting the cap onto my camera lens and shooting a "darkened" frame that way, I'm at the same level or even higher because of saving the time of shooting those "unexisting" dark frames.)
