Arp 76 (GLXGRP)

DSS
© DSS II (red) - 15×15'
Name: Arp76
Type: GLXGRP
Constellation: Vir
Coordinates: 12h36m48.00s / +13°11'30.00"

Group Members:
IC3583 (UGC7784) v12.8 mag 2.2x1.1'
M90 (NGC4569, UGC7786) v9.5 mag 9.9x4.4' (23°)
The fainter IC3583 is located NNW of M90.

8" f/6, 80x, Bortle 4-, NELM 5.8+, SQM-L 21.0
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.

Arp 116 (GLXGRP)

DSS
© DSS II (blue) - 12×12'
Name: Arp116
Type: GLXGRP
Constellation: Vir
Coordinates: 12h43m37.00s / +11°34'00.00"

Group Members:
M60 (NGC4649, UGC7898) v8.8 mag 7.4x6.0' (105°)
NGC4647 (UGC7896, H3.44) v11.3 mag 2.9x2.3'
4.5" f/8, 60x, Bortle 6, NELM 5.3, SQM-L 19.7
Messier 60: At 60x very bright center with fainter, slightly oval halo. At 28x Messier 60 appeared more roundish. Easily seen with direct vision.

NGC4647: Quite faint, roundish, evenly bright. Only seen with averted vision.

EASY
8" f/6, 80x, Bortle 4, SQM-L 21.1
SQM-L in the target region: 20.8

Messier 60: Very bright, round, extended core area with large, fainter, round halo. Of course also well visible at low power.

NGC4647: Roundish, evenly bright. Evident with averted vision.

Arp 120 (GLXGRP)

DSS
© DSS II (blue) - 12×12'
Name: Arp120, The Eyes
Type: GLXGRP
Constellation: Vir
Coordinates: 12h27m42.00s / +13°02'00.00"

Group Members:
NGC4435 (UGC7575, H1.28.1) v10.8 mag 3.0x2.2' (15°)
NGC4438 (UGC7574, H1.28.2) v10.2 mag 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.

8" f/6, 37x, Bortle 5
NGC4435 appears with nearly stellar, bright core, NGC4438 is slightly elongated with also bright core.
EASY

Arp 134 (GLXGRP)

DSS
© DSS II (blue) - 15×15'
Name: Arp134
Type: GLXGRP
Constellation: Vir
Coordinates: 12h29m50.00s / +07°58'30.00"

UGC7636 (PGC41258) v14.8 mag 1.1x0.9'
The much more fainter UGC7636 is located southeastern of M49, western of a brighter star.

80mm f/6.25, 25x, Bortle 7
M49: Still visible with direct vision but less evident. Roundish, brightening toward the middle.

EASY
8" f/6, 37x, Bortle 5
M49: Very bright, slightly oval nucleus with faint halo.

Arp 271 (GLXGRP)

DSS
© DSS II (red) - 8×8'
Name: Arp271
Type: GLXGRP
Constellation: Vir
Coordinates: 14h03m26.00s / -06°03'00.00"

Group Members:
NGC5426 (UGCA380, H2.309) v12.1 mag 3.0x1.7' (173°)
NGC5427 (UGCA381, H2.310) v11.4 mag 2.9x2.2' (170°)
8" f/6, 80x, Bortle 4, SQM-L 21.2
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.
