My version below:

HSO_Pacmanv3.png

Processed in PixInsight (StarXTerminator, BlurXTerminator, Seti Astro: Statistical Strech; DBE at SII channel) and then Photoshop and many layers. Stars stratched with GHS. 
If you like it and need more details about processing steps just let me know. 

Very nice data for training and practice! Please consider publishing your data for future download on AstrophotoMarket.com !

Like others - did not give the data as much time as one might for one´s own image - but was happy to download and give it an hour nonetheless. There will be so many different variations here it will open your eyes..... no interpretation of the data is wrong and none arePacMan.jpg 100% correct either.......but I hope you will get something out of all the replies.

Richard:
I'm offering up 3 Tiffs of the Pacman nebula roughly 17 hours of data and time! Why? because I think I've reached a point where my processing skills arent getting me the results I'd like, and I think from the data there should be more to get. So, I give it to you to do your best and show me what I might be missing.

I ve stacked the tiff files in DSS, roughly 5 hours of each filter, Ha, Oiii, Sii, with darks, flats, bias frames, I have only performed a star align and saved from pixinsight as a standard tif, any difficulty let me know, they are located on my Drive Here:

please post your results either in the Forum or on your own astrobin page referencing me. Thank you!

Taken with an asi1600gt and a WO FLT132, astrodon filters from a bortle 5, heres the link to my version of the pacman, look forward to critique!https://www.astrobin.com/thz931/

Hi Richard,

Here's my attempt. I found part of the data had a peculiar noise pattern which made the processing harder than I am used to. i see you used an ASI 1600, that might be the reason behind that. I think I managed to bypass that a little. I did an SHO palette.

Workflow:

Noise reduction in linear phase (I never do that in the linear phase but noise was so high I could not cleanly remove the stars otherwise and I needed them linear for the NB to RGB Stars script)
Channel combination (linear)
Unlinked Stretch
Normalization
Curves
Neutralize background
Separate channels, convolute in order to get rid of that relentless noise
Equal intensities of Ha and L
Use Ha as luminance and create an LRGB with convoluted channels
Color noise reduction
Neutralize background again
Create RGB stars from NB with Seti-Astro script.Image47.jpg
That's all.
