Phil,
Of course we are still reading! That image looks great - was it calibrated?
Like Jeanette I don't fully understand why some images look so noisy. For sure high ISO is one cause. Anything above ISO 400 and the noise seems out of control.
I have also noticed that DeepSkyStacker wants to create diagonal banding in noisy areas.
M83, ISO400, 600 Sec, Canon 500D, f/7.5 Refractor, 50% resize - not processed.
