Conditions in the target region: SQM-L 20.7
I only focused on the bright Messier 90. Very elongated (1:4) with bright, very compact core. Core area also slightly elongated. Otherwise rather evenly bright.

Group Members:
NGC4435 (UGC7575, H1.28.1) 10m8 3.0x2.2' (15°)
NGC4438 (UGC7574, H1.28.2) 10m2 8.5x3.0' (20°)
These galaxies were first called 'The Eyes' by Leland S. Copeland in 1955 in a 'Sky & Telescope' article, based on their visual appearance.

Arp 271 (GLXGRP)

Coordinates: 14h03m26.00s / -06°03'00.00"

Group Members:
NGC5426 (UGCA380, H2.309) 12m1 3.0x1.7' (173°)

8" f/6, 80x, Bortle 4, SQM-L 21.2
Conditions in the target region: SQM-L 20.2
At 37x both galaxies appeared together as oval brightening, whereby the brighter, northern NGC5427 was already visible as round, evenly bright, but faint nebula. NGC5426 was barely seen with averted vision. At 80x the galaxies were well separated. NGC5426 appeared slightly elongated and also evenly bright.
