SL 250 (Open Cluster)

RA 05 07 51.1 Dec -69 26 08 Mag 13.1 Size 1.00′

16″ at 228x: SL 250 appears as a faint, round, even, glow, ~20″ in diameter, and with no stars resolved.

LH 30 (OB Association)

RA 05 08 14.0 Dec -69 13 24 Size 2ʹ

16″ at 228x: This is one of the Cloud’s stellar associations that might well be a “pretty little group of random stars” that one passes on the way to somewhere, but when you stop and look at it for what it is, its “stellar association character” reveals itself… round, 2′ in diameter, with half a dozen stars (one nice bright mag 12, the rest 13-14 mag) distributed across it, some tiny pinprick stars, the soft haze of unresolved stars… it’s actually quite a little beauty.

SL 266 (Open Cluster)

RA 05 09 07.4 Dec -69 43 01 Mag – Size 1.10′ x 1.0′

16″ at 228x: This extremely small and extremely faint cluster, which required averted vision to see, was only picked up because it lies 1.7′ W of mag 8.4 HD 34170.

SL 266

SL 268 (Open Cluster)

RA 05 09 14.7 Dec -69 35 17 Mag 12.1 Size 1.60′

16″ at 228x: SL 268 is a pretty cluster, appearing as a bright, irregular glow, ~30″ in diameter, with no stars resolved. It is located just north of a long, 5′ shallow arc of five mag 12 + 13 stars that open towards the cluster.

SL 268

SL 276 (Open Cluster)

RA 05 09 55.5 Dec -69 21 16 Mag 12.9 Size 1.30′ x 1.20′

16″ at 228x: Located in a line with cluster SL 280 lying 1.5′ NNE and mag 8.7 star HD 34276 lying a further 1.8′ NNE, SL 276 appears as a faint, round haze, ~18″ in diameter. It appears remarkably similar to SL 280.

SL 276

SL 280 (Open Cluster)

RA 05 10 16.4 Dec -69 20 32 Mag 11 9 Size 1.10′ x 1.00′

16″ at 228x: Lying centre in SSW-NNE line with mag 8.7 star HD 34276 1.8′ NNE, and the cluster SL 276 1.5′ SSE, this cluster appears as a faint and round haze, ~18″ in diameter. It appears remarkably similar to SL 276.

SL 280

SL 296 (Open Cluster)

RA 05 10 55.8 Dec -69 33 33 Mag 13.1 Size 0.95′

16″ at 228x: Mag 7.6 HD 34437 lies 2. 8′ ENE of SL 296, and its lovely slighly yellowy spark certainly enhances the scene with SL 296 appearing as a faint, very small, round glow, 10″ in diameter. A mag 12.4 star lies 1′ SE.

SL 296

SL 304 (Open Cluster)

RA 05 11 59.5 Dec -69 12 06 Mag 13- Size 1.20′ x 1.10′

16″ at 228x: SL 304 appears as a very faint, round, smooth glow, ~15″ in diameter. HS 167 lies just off its SSE end, and appears as an exceedingly small and faint glow, picked up with averted vision.

SL 304

HS 169 (Open Cluster)

RA 05 12 10.6 Dec -69 16 43 Mag – Size 0.7×0.6

16″ at 228x: This tiny cluster is quite easy to locate because two ~mag 13-14 stars and stellar H88 211 lie in a convenient NW-SE line just beyond the western boundary of the glorious N113 complex and HS 169 lies 2.3′ NW of H88 211. The cluster apepars as a very faint, and very small, droplet of dim light.

HS 169

HS 174 (Open Cluster)

RA 05 12 31.7 Dec -69 45 17 Mag – Size 0.8′ x 0.7′

16″ at 228x: HS 174 appears as a very faint, round glow, ~15″ in diameter, buried in the bright glow of the bar, but it is easy to locate thanks to mag 10.4 HD 269202 that lies just north of it.

HS 174

H88 211 (Open Cluster)

RA 05 12 34.43 Dec -69 17 13 Mag – Size 0.7 x 0.6

16″ at 228x: This cluster appears as the third, and slightly brighter “star” in a short NW-SE line just beyond the western boundary of the beautiful N113 complex.

H88 211

NGC 1872 (Young Globular Cluster)

RA 05 13 10.0 Dec -69 18 45 Mag 11.0 Size 1.7 Age –

16″ at 228x: This young globular cluster is gorgeous. Bright, round, 1′ in diameter, with a beautifully bright core and a halo that is slightly mottled. A couple of ~mag 14.5 stars are resolved on the edges of the halo. The globular inhabits a very interesting corner of the bar, being just a short hop from N113, a striking complex of H II regions.

NGC 1872

LH 39 (OB Association)

RA 05 13 49.4 Dec -69 32 42 Size 6ʹ x 2ʹ

16″ at 228x: A charmingly delicate arc-shaped association, whose five bright stars and haze of unresolved stars stands out nicely against the glowing background. The five mag 11-13 stars delineate the 4.2′ E-W arc which is open to the south. The mag 11.9 Wolf-Rayet star, Brey 18, lies in the centre of the arc, just north of what looks like a fuzzy mag 13 star and which is actually BSDL 952.

LH 39

N114A (Emission Nebula)

RA 05 14 01.0 Dec -69 31 42 Mag – Size –

16″ at 228x + UHC filter: N114 is a huge and exceedingly faint complex with N114A as the only brightish section, but alas the nebulosity is all but washed out by the mag 11.6 ionising star, HD 269244 which lies buried in the centre of the nebulosity. Averted vision suggested some vague hints of nebulosity, but it was extremely faint.
