NGC 5566, 5560 and 5569
This triplet of interacting galaxies are really beautiful, with each having very distinct shapes. This was a very faint target and even after 6 nights there was not as much data as I would have liked.
I used a Celestron Edge HD 925 with a 0.7 reducer, an ASI 2600MC Pro. I managed to get 17 hrs 45 minutes total exposure time, with 213 x 300s subs. I processed it in SiriL, Starnet, GIMP & G'MIC.
