My goal with this image was to emulate the resolution that Hubble achieved with the core--to reveal space between the stars and not just a blinding glare--kind of like some of the excellent images of globulars taken with very large scopes when the cluster fills the FOV.  Image particulars in the links

I just noticed the particulars are not with the images so: TOA 130 with ASI 1600 and Astrodon Series E Gen 2 filters.  This is an RGB composition with a synthetic luminance made with the green channels stack (The green stack  had a FWHM of less than 2.0, which is good for me, so seemed appropriate).
Red: 25 5 min
Green: 40 5 min
Blue: 32 5 min

2 versions--not sure which I prefer--number 1 for normal mviewing and #2 for full resolution I think.  Let me know if you concur.
