so many great replys, thanks.
I usually shoot at around ISO 800, and thats what these images are. I know these images are filled with noise, but i was just messing around with exposure times.
The problem i always find, is that apart from noise, images always look like a washed out grey, and what was in colour, ends up looking monochrome. With stacking, i should have thought the images would have gotten brighter, and colours more intense, but it just ends up looking really washed out. TBH, i am starting to lose heart somewhat.
It seems that any exposure over about 3 mins, starts getting shockingly bad noise, so for a 3 mins shot, whats the point in guiding?
I am wondering if IRIS would do a different/better job
any more input welcomed.
and yes, i know its not the Lagoon nebula
