I also re-read your question, your Darks are always the same length, ISO and temp as your Lights, I think maybe you are refering to Bias shots, they are always taken at the shortest possible exposure with the lens cap on, they are not temp dependant but must be the same ISO as the remainder of your shots.
Not sure what program you use for combining, aligning etc, I use ImagesPlus 3.50 and everything is automatic.

Thanks very much for the info John, I really do appreciate it.
I also have IP 3.50 but only got it recently and have not used it. I have been working through the instructional video's that came with it.
I have been using IP 3.60 camera control to take star trails with my 450D.
I intend to now try some wide field piggy back images with the 450D on my scope and then prime focus through my scope, steep learning curve.
All of my deep sky work in the past was on 35mm film.
Regards
Trevor
