The black point.... I didn't express myself properly. You would like a darker background, correct?
Thanks!

It's a bit hard to make predictions here because I don't have the fits file.The histogram looked a bit narrow to me, which was why I suggested the stretch, it may not be the right thing to do. I also think that stretching may brighten up the core too much, so you could try HDRMultiscaletransform to reduce the dynamic range. Don't get me wrong now. I think the image is very good as it is. I was just suggesting some of the things I would try--no guarantee that it will improve things.
Re black point. Slide to the right to nearer the base of the histograms. It may chop out some of the background noise or it may make the background too dark--experiment!
