Thankyou for your comments Mickoid and Chris,
I didn't use any filters for this shot. I thought that imaging under a dark sky would be optimal to take in unimpeded light. I have a UV/IR cut filter and a Hutech LP filter that I like to use in suburban skies but didn't think it would be Necessary.I could be wrong though. One thing is for sure the DSLR didn't suffer from the usual heat build up! Chris, I would have liked to take more subs but as is the case it took me what felt like an eternity to get the Newtonian setup polar aligned and balanced ready to go. It always seems that way when youre setup in unfamiliar territory. But none the less 26min gave a result that I could be happy with. Besides, I didn't have much more incentive after midnight the temp dropped below zero and I was beginning to lose feeling in my fingers and toes hehehe.
