I have done a repro of this one to address some of the critiqued points. Stars rounded, faint perimeter of the galaxy pushed hard.
Its now rather a unique view.
I took this image over several weeks and 4 or 5 hours a night.
Again, there were some periods of good seeing during the imaging.
The points of interest in this image are apart from the new stars in the blue/pinkish regions but there is a blue jet at about 8 oclock. I first noticed this on an image I took of Cent A with my TEC180 from my dark site.
I also am interested in this image as it shows the dust band which crosses Cent A also extends a large way under the ellipitical galaxy itself. So vast amounts of dust have been spewed under the galaxy from this merge. I haven't noticed this spread of dust in other images and seems to be the advantage you get from 27 hours!
Planewave CDK 17, Proline 16803, STi and Lodestar guiders, Paramount PME mount in my home observatory. Luminance exposures were typically 15 minutes, RGB 2x2 and 10 minutes although I did several hours of RGB 1x1.
I think for galaxies in future I will shoot RGB 1x1 and 10 or 15 minutes to get maximum little details and resolution.
This is an extreme version of the image maxed out to show extent of the galaxy:
