Some folk like magenta stars in NB images but this leftover from the SII integration can draw too much focus away from the object.
Tou can make a dramatic change simply by opening the 'selective colour' dialogue in PS, selecting 'magenta' from the drop down menu and dragging the 'magenta' slider to -100%. You can achieve the same result in PI under histogram transformation.
Obviously, an even better result can be achieved if you isolate (mask) the stars.

Thanks Martin I did have a quick play with that and got odd looking halos but I will give it another go thanks
Nice one Mark.
Some LRGB will get rid of the purple stars. Melbourne is in nuclear winter at the moment, so good to see Sydney has some cloudless nights at least.

Yes I grab what I can while its clear if only the sky was dark as well
Thats a really nice image. I like the colours, very strong and the pillars are pretty cool
The blacks seem clipped around the darker areas towards the top and tweaking star masks might help with some of the smaller stars if you are desperate to lose all of the magenta
On the RGB, give it a go. I wouldn't bother with the L but short RGB subs should be fine if you are just looking for star colour, subject to whatever your gradient removing tool of choice is. The last 2 cluster images I did where taken from a very short bus ride away from the CBD. 3 minutes subs tops, no LP filters, but not sure what that translates to with your ASI1600.

Thanks David I will play around with some rgb for the stars I was just happy to get good colour to start with I have 3 more objects I am desperately trying to get data for at the moment as well ...before moon and clouds put a stop to it again
Was this with the 10" RC? What location and exposure details?
Best,
Mike
Yes the RC10 ASI1600 it was taken in my backyard suburban Sydney again
It was just 1hr Ha as I had that from previous image and added 1.5hr S2 O3 each. Probably a couple more hrs Ha may be helpful but i just wanted to see what it would look like
Lovely colours Marke, looks like you are fiddling and some good suggestions have been made, keep fiddling...Rome wasn't..err?..burnt?..in a day...I meant built

Thanks Mike I'm trying to fiddle without starting any fires mate I've learnt a lot lately not to mention the frustration
