SL 348 (Open Cluster)

RA 05 16 54.4 Dec -68 36 38 Mag – Size 1.3′ x 1.1′

16″ at 228x: This very faint cluster has a handy pair of bright markers – it lies 3.8′ WSW of mag 7.6 HD 35230, and 1.6′ NE of mag 10.4 HD 269279. The cluster appears as an exceedingly faint, small and round haze; little more than a slight brightening against the background glow.

SL 348

BRHT 33a + H60b 1 (Binary Cluster)

BRHT 33a: RA 05 16 54.4 Dec -68 52 35 Size 0.5′ Sep 1.29′ PA 77°

H60b 1: RA 05 17 06.9 Dec -68 52 25 Size 1′

16″ at 228x: This is a pretty little binary cluster, lying in an attractive arrangement of stars. H60b 1 is the bigger and the brighter of the two clusters, appearing as a fairly bright, round, even glow, ~30″ in diameter. BRHT 33a, lying to the west, appears as a very small, very faint, round glow; it almost looks like a shadow cast by its companion. No stars are resolved in either cluster. A mag 11.8 star lies 54″ SW of BRHT 33a.

SL 349 + 353

SL 351 (Open Cluster)

RA 05 16 59.9 Dec -68 40 58 Mag – Size 0.8′ x o.7′

16″ at 228x: SL 351 appears as a very, very faint, and very, very small, roundish glow, barely standing out against the bar’s shimmering glow.

SL 351

SL 359 (Open Cluster)

RA 05 17 49.0 Dec -68 28 24 Mag 13.7 Size 1.3′ x 1.1′

16″ at 228x: This little cluster is certainly keeping some gorgeous sparkling company, and it’s not difficult to ignore its faint little glow and enjoy all the sparklers set against the bar’s rich glow! Mag 9.2 HD 35183 lies 2.4′ W; mag 8.4 HD 35294 lies 1.4′ ENE and to its east lie a gorgeous gathering of stars, elongated NW-SE 3.4′, and including a couple of mag 10 stars, three mag 11 stars and a sprinkling of fainter stars. The cluster appears as a very faint glow, round and 15″-20″ in diameter.

SL 359

NGC 1917 (Young Globular Cluster)

RA 05 19 03.4 Dec -69 00 06 Mag 12.3 Size 1.7′ Age –

16″ at 228x: This young globular cluster appears as a fairly faint, round, glow, 50″ in diameter. The glow is smooth and even. No stars are resolved. A Classical Cepheid star lies 7.5′ ESE.

NGC 1917

SL 390 (Open cluster)

RA 05 19 54.3 Dec -68 57 47 Mag 12.5 Size 1.1′

16″ at 228x: SL 390 appears very faint, very small, round, just bigger than quasi-stellar.

SL 390

SL 397 (Open cluster)

RA 05 20 11.2 Dec -68 54 18 Mag 12.2 Size 1.0′

16″ at 228x: SL 397 is an attractive little cluster. It appears as a fairly faint glow, ~25″ in diameter, somewhat elongated N-S. A ~mag 14-14.5 star is resolved on the SW side. A mag 12.4 star lies 37″ SE, and a mag 12.9 star lies 56″ SSW.
