The great depth you've achieved has nailed the faint and distant background structures - beautifully done - but you've managed to keep the overall sense of what's bright and what's dark, which is really important.
Some might notice that the stars have both asymmetric black and magenta circles around them, which could be removed if desired.
Placidus (Mike and Trish): Your comment means a lot to me. Your images are among the very best posted under this forum and your work is closer to perfection than mine. I always strive for perfection, and I have improved slowly over the years. I doubt I will ever achieve perfection.
That's a top shot Murray. The details in the highres are very good and smooth as well. I reckon as Mike pointed out too a repro is in order for the stars. Did you use a minimum filter or deconv? If you leave your stars alone with a mask and sharpen only the nebulosity you'll get a corker. You already have the SNR to do that.
