Thanks, Nico. I had been contemplating a certain noise reduction filter for some time. On the strength of your suggestion, and after seeing your version in Pending, I bought the plug-in this morning. I used it on this image, and I must agree that it significantly improves the appearance. I deleted the version you put into Pending, as it is no longer needed.
Charlie. This is really excellent... and of course just perfect for the topic. I like the strong contrast and the super compostion. Great stuff.
I could not resist the temptation to mess around a little to see if one could get some of noise reduced. My attempt is posted in pending, but I this is done with the clear understanding that you ignore that version with pleasure. No offense will be taken. You are the artist and the owner of the shot, after all.
