Thank you very much for that. Is it also beneficial to take bias and flat shots in a similar way (e.g. averaging 10)?
I was previously using ICNR which worked well but unfortunately it used up a lot of the evening time just taking darks. I recently converted my 350D to be temperature controlled so I'm hoping it will allow me to produce and use a dark, bias and flat library to give me more capture time (and hopefully more sleep

). Looks like time to put it to the test

.
Thanks again,
Markus
