NGC 1777 (Open Cluster)
RA 04 55 48.0 Dec -74 17 00 Mag 12.8 Size 2.4′
16″ at 228x: Lying 38′ N of lovely orangey mag 5.5 Eta Mensae, NGC 1777 appears relatively bright, irregular, 1.2′ in diameter, slightly elongated N-S. Very unusually, there is a lovely double, HJ 3722 superimposed on its east side (mag 11.2/11.5 at 31″ separation). The cluster is bracketed by a mag 12.5 star lying 2.2′ SE and and mag 13 star lying 1.7′ NW.

NGC 1956 (Background Galaxy)
RA 05 19 36.1 Dec -77 43 45 Mag 13.1 Size 1.9′ x 0.8′ SB 13.5 PA 68°
16″ at 228x: To my eye, edge-on galaxies are elegant and enigmatic, and this background galaxy is a lovely edge-on! It is ~1.5′ x 30″, elongated WSW-ENE, with a small, bright, round core surrounded by a much fainter halo; their ends beautifully rounded.

NGC 1956
SL 433 (Open Cluster)
RA 05 22 18.0 Dec -74 36 18 Mag – Size 1.7′ x 1.5′
16″ at 228x: SL 433 appears as a faint, round, very diffuse glow, ~30″ in diameter.

RA 05 23 06.0 Dec -75 26 48 Mag 13.9 Size 1.4′
16″ at 228x: IC 2134 appears fairly faint, round, smooth and even, 20″ in diameter, no stars resolved.

IC 2134
SL 576 (Open Cluster)
RA 05 33 13.0 Dec -74 22 06 Mag 13.7 Size 1.6′
16″ at 228x: SL 576 appears as a fairly faint, round glow, 20″ in diameter.

IC 2140 (Open Cluster)
RA 05 33 21.0 Dec -75 22 36 Mag 13.5 Size 2.3′
16″ at 228x: IC 2140 appears as a faint, round glow, 1.4′ in diameter, with a slightly grainy appearance, and brightening slightly to the centre. A couple of ~mag 15 stars are resolved around the edges and a mag 14.3 star lies off the east-northeast edge.

IC 2140
SL 620 (Open Cluster)
RA 05 36 29.0 Dec -74 24 18 Mag 12.6 Size 1.9′
16″ at 228x: SL 620 appears as a fairly, round, hazy even glow, ~40″ in diameter. A couple of ~mag 15 stars are resolved on the northeast edge.

IC 2146 (Open Cluster)
RA 05 37 46.0 Dec -74 47 00 Mag 12.4 Size 3.3′
16″ at 228x: IC 2146 appears as a fairly faint, round and hazy glow, 1.3′ in diameter. A couple of mag 15 stars are resolved at the southeast edge.

IC 2146
IC 2148 (Open Cluster)
RA 05 39 11.0 Dec -75 33 48 Mag 14.2 Size 1.3′
16″ at 228x: IC 2148 appears as a very faint, round, and diffuse glow, 25″ in diameter.
