I struggled with this one I must say - I had in camera NR on - I would be curious to see what others can make of it - no flats taken and it's a single shot - when I try to push for the fainter details I see the noise come out - plus the background moonlight and light pollution don't help. I am N of Sydney so shooting into the glow for Eta C. I have attached the best unproced version I can mange as a zip. It was shot as a RAW, converted to TIFF with the Canon utility, and to fit under 500Kb zip limit I have resized (quarter size) and Jpeged (sorry), appreciate any/all feedback....

Hi John,
Unfortunately, I think using jpeg to get the files size down has lost some detail in the compression. Also, the best way to reduce noise is to take lots of subframes. A single three minute shot in this warm weather will be quite noisy, even with the in camera noise reduction on. The signal to noise ratio improves by a factor of the square root of the number of subframes. So it is worth taking the extra frames. Of course being washed out in the LP doesn't help either.
cheers
