Well, I used my old darks for last nights shooting of the Eagle nebula. I got 42 minutes worth and am not terribly happy with it.
Have a look
here at the nebula thumb and look at the first one, M16 Eagle nebula, to see what I'm talking about.
I think I will have a go at taking a few lights, then darks, then more lights etc.
It seems like a real pain in the butt to do, but this IS a game of patience and perfection, so I'm up for it.
This just means I will probably have to resist being greedy for multiple targets in one night, and just dedicate myself to getting ONE GOOD ONE in a night.
I just get so excited....
Baz.
