That is a remarkable improvement Martin. This is one of my favourite galaxies and you have done a superb job here. I really like your repro - beautiful.
Its interesting to me as the change from the first to the 2nd is something I need to do with some of my earlier images. I also have tended too often to push the data too hard and bring up too much blotchiness and noise in an attempt to make the dim data brighter and it ends up degrading the overall look of the image.
There is something to be said for subtlety and there is no substitute for long enough exposure times.
Greg.
