This will not be popular on Astrobin (which is essentially a beauty contest). It was difficult to process, but is super interesting. https://www.astrobin.com/du9uge/

NGC 1395: A Voracious Eater of Galaxies
You might think this is an ordinary elliptical galaxy, but not true. It has a very large number of globular clusters (6,000, vs around 200 for the Milky Way) which indicates that NGC 1895 has gobbled quite a number of dwarf galaxies. And in 1983 a faint shell structure was discovered, which was probably caused by NGC 1395’s recent accretion of a smaller galaxy. If you look set the image carefully, you can see at least seven dwarfs.
NGC 1395 also satisfies five criteria of Catalog of Southern Peculiar Galaxies and Associations, by Halton Arp and Barry Madore.
Category 8-Galaxies with Apparent Companions
Category 15-Galaxies with Tails, Lumps, Loops of Material or Debris
Category 17- Chains
Category 20-Dwarf Galaxies (Low Surface Brightness)
Tech Notes for ASA 500/3.6:
ASA Newtonian, 500 mm aperture, 1900mm focal length, F3.6
FLI Proline 16803, 9 μm pixel, 4096 X 4096
ASA DDM85 equatorial mount
Processing with PixInsight, StarTools, and Affinity Photo
