Well after looking at my NGC 1097 again (errr and Martins ridiculously good version )...ummm...I decided to redo the processing...meah just cause
There were a few issues apparent so I removed the slight megenta cast, improved the star colour, improved the colour dynamics of the galaxy and brought out the HII regions a little better, tightened the stars, revealed a little more in the very core without disrespecting the light ...and improved the background through a variation of DDP on the Lum (no noise reduction though)...phew...
I like the colour better in this version, Mike. In case you're looking for reasons to do another repro the subtle shells around NGC 1097A aren't as visible in either version as I've seen in a few other images.
I must get my NCG 1097 finished one of these days so you can poke holes in it, Mike I have quite a queue of images that need to be processed. Unfortunately, I've been spending too many nights catching up on my day job.
Don't recall seeing the previous version Mike, but this rendition looks the goods. You running AO these days? The detail in the core is something I'd expect from a much longer focal length and image scale than 1120mm scope.

He he and yes I knew about the shell and it is there.. just not quite as delineated as I would like...probably needs more exposure and better seeing to reveal that one well

Cheers Jase, appreciate the feedback
AO??? naaah not in the mix yet, nor is PEC or ProTrack for that matter...just NJP power

Mike is using an ICX694 with smallish pixels (4.54 microns) so his image scale is around 0.8 arcsec/pixel despite the short focal length.

Yes, that is true and it has helped with galaxies and PN's for sure...but still no real substitute for longer FL + AO, PEC and ProTrack on thse smaller objects..one day...one day the fast F3.8 is good though.
