Either way plenty of good in the image too

I had another look at it more carefully comparing it to an earlier version in the processing sequence and you are right something has smoothed out the galaxy unintentionally. The earlier versions before that step were sharper.

So I have taken on the various comments about softening the brightness and edges of the stars, making it sharp etc and put it all together and I think this final version seems to address them all. Overall I think this is the best M83 I have done so far even though it was less data.

But I do see what Mike is talking about - the inner portions look a bit over smoothed. Not sure why it would look that way without noise reduction though Did you apply sharpening, unsharp or other filtering to the central bits?

Cheers Marcus. As mentioned above I looked again and you are both right there had been some smoothing that entered in unintentionally at some point. Corrected all the various points now.
