Very nice image for such a short capture period.

Re: Omega Centauri in a very short capture.
Wow. That is a very good image showing stars right to the core and a short imaging time. Of course can't see that object from here -- our best is M13.
Did you need to use high dynamic range processing in PI to reduce the relative brightness of the core?

Re: Omega Centauri in a very short capture.
Hi Tim, actually what I did was just very slow stretching, manually, and then a very small and highly diffuse mask, just enough to compensate the stretching, so the core could get something like 20% stretch and the outer part the 100%, it was the only way I imagine to create a sort of distribution of intensity in the strength of the stretching, to say it in a way.
Re: Omega Centauri in a very short capture.
Thanks Nick, the cluster is quite luminous, so I am planning a longer exposure, in total, but stacking exposures of no more than 10 to15 seconds each. I have some friends that actually mix, short with long exposures.
Re: Omega Centauri in a very short capture.
Very cool capture!
I now and then do some experimenting with it too but then in the realms of lucky imaging with <1 second exposures with of course the big disadvantage of very long stacking times :p
