Thanks everyone for looking. It really is an interesting object. I thought the "black eye" came from the appearance, but I gather from Wikipedia and elsewhere it also relates to the theory this one was whammied by another galaxy quite some time ago, with enough disturbance some outer material is now counter-rotating.

Nah, not elite Humayun, but pleased to get right in close

I tried hard not to push too hard Jase, which I am frequently guilty of! I thought including the lum only might be of interest to some. Thanks!

What alignment software are you using? There is evidence on some of the stars of colour misalignment of the subs. I find CCDstack CCDis plug in to be unbeatable for accurate alignments.

I've pondered this a bit on this one and other images Greg. I'm using Pixinsight, and it's certainly possible other software might come out differently. I'll have to have a look at CCDStack - always open to anything that helps.
I think ultimately what you're seeing here though is the effect of poor (actually a bit above average for me) tracking that has been mathematically averaged (median'ed). I'm frequently amazed how well PI combines down a series of subs where some are great and some average with oblong stars and ends up with (generally) very round stars. Nothing is perfect though, and I think the colour bleed you see is where the oblong stars on a particular colour haven't averaged out the same as the other filters. I left out a couple of smeared Lum frames that weren't up to scratch, but the colour frames were generally pretty good, however they were binned so less room for error.
Gosh I'd love to chuck the Newt on a PME just ONCE to see what is possible. Seeing, collimation, focuser scatter and all sorts of other things coming through here too of course....
EDIT: I guess this is what Ivo terms "the use of raw computing power to help overcome limitations of your current equipment and budget"

I recall observing this galaxy visually many years ago and being fascinated with that dust lane. Thanks for the view.

Go for it Martin! I think this one and the Sunflower galaxy are frequently overlooked by imagers down under.
