Hi again everyone.
A few nights ago I managed to do some imaging after moon set (2 nights) with about a hour or so of dark sky before twilight starts. Seeing was fairly good and the sky very clear.
This picture consists of 22x4 min at iso 1600 with my 6" newtonian f5.6.
I don`t usually use iso 1600 but I thought I would give it a go and see how much noise there would be with many exposures. There was still plenty of noise and it took some processing in PS to get most of it out.
Picture has had quiet a go (about 1hrs worth) to get it looking the way it does now in PS. I won`t be doing to many other iso 1600 shots and shall stick to my favorite speed of 800 iso.
Quiet happy with the final picture. Will do a 800 iso as soon as theres a new moon and no cloud..
Cheers Gary
