Yeah, never waste your time doing OIII on galaxy shots. Even Ha can have little effect unless there's a lot of HII emission going on. Even then, only apply Ha to the galaxy (limiting to the emission elements if you can) and not to the whole frame, so your stars retain RGB colour.
Also think about doing a bit of deconvolution to reduce star bloat and add detail. Careful though, it's easy to overdo decon.

Thanks Marcus, just the sort of info I need, will do as you suggest.

As Marcus pointed out the Ha is going to damage the stars with little gain. There is a little bit of Ha in 2997 but not a lot.
Overall an excellent image that you can build future images on.

Thankyou Greg.
It looks like the Ha did stuff up the stars. Will have to start the processing all over again.
I can't beleive just how much time it takes, not to mention keeping track of what's what...
