M17 Swan Nebula in LRGBHa

Hi, my first time in this "experienced" area; however I am still quite new to this hobby, particularly image processing. Comment/suggestion/advice are welcome and grateful.

Here is the Swan taken over several nights of late July in Sydney. Altogether about 6 hours of LRGB and Ha. I found LRGB alone is really lack of detail; adding Ha in is a real challenge and headache for processing, background and star colours are odd.

6" refractor at F/5.3, guided with a small guidescope, acquisition was mostly done by CCDAutopilot through Maxlm, processed with PixIninsight and Photoshop.

Thanks for looking.
David
