Nice shot Paul. The TSA frames it very well and is such a sharp scope so that is great. Tracking is fabulous. I agree though with Mike.

I used to use Shadows/Highlights a lot but now I am very careful with using it. Its a handy tool but like the minimum filter and the unsharp mask it is quite limited and best used inverted masked so it can be toned down afterwards. It can easily "flatten" an image so it loses its varying dynamic range. Too much selective colour can do a similar thing. The much brighter core is what this object looks like.

But that is a really minor point in an overall excellent image. A bit more exposure would give the colours more depth.

In a way we consider Omega Centauri an "easy target" but really it is quite a handful to take it to that exceptional level. I haven't captured to a level I am happy with yet.

Your image is better than the recent NASA APOD of the same object though (not that that would be hard).

Greg.
