Hi
Wondering if someone can help
The image below is a very tight crop of NGC 5189 (Dunlops Best). The image was shot on the night of the full moon (how corny does that sound) so didnt expect much but on processing today I was reasonably happy. A bit noisey and I need better data but...My question though is are the star colours rights or am I happily processing hot pixels?

This is basically 6 subs of 1200 seconds at ISO 400 with in camera darks using a Canon 30d and a CLS clip in filter on a SWED100. Stretched in CS6.
I like In camera darks because you are doing reduction at approximately the same temperature as the light, but if they are not effective then I wil l have to move to taking seperate darks.
Any suggestions??
