processing 2 nights ?
      #6009602 - 08/06/13 02:30 PM

So far I have taken 2 nights of pictures of M31 . First night : 2 hours 45 min ,in 3minutes @ 1600 iso + 25flats + 25darks( at 28Celcius ) and one master bias.
second night : 2 hours of 3 minutes @ 1600 iso + 25 flats + 25 darks ( at 19Celcius ) and the master bias.
My question is ,do I put everything in DSS ? Will DSS figure out the different sets of darks and apply it to the good lights ?? I know it won't accept 2 different master darks ,thats why I ask....
Thank you for helping !
Maxx

Do a search for groups in DSS help. This will answer all your questions.

bouffetout: There is a Groups feature in DSS - put each night's files into a separate group (along with it's calibration files) and DSS will do the calibration of each group/night separately and then stack all of the files together.

This is the technique I used as well. However, I've also seen people stack sets separately and stack them manually later in Photoshop. Specifically I've seen people do this when there's a very high dynamic range in the photo, and they took a set of short exposures to get detail in otherwise overexposed regions.
