Excellent Mike. I think the composition is bold as I have no idea what you were trying to make a feature. No feature galaxy is true center, so I assume you were trying to fit as many galaxies into the FOV. Looked the optical configuration FOV in TheSky. I don't think you could have framed it any other way to maximise the quantity of galaxies. Personally, I think you've got to alter your routine to incorporate a little noise control. This would certain take your output quality to the next level and yes, you can still use noise control techniques without destroying your background faint fuzzes. Seriously, don't know what's holding you back.
Shame about the internal reflection too. If you're keen, you can chase it PS, but it will take. Again, thanks for the swim around. Certainly a pleasure to see the details on display. Well done.
