Type: open cluster, 12r
Mag: B=10.43, V=9.4
This 11th magnitude open cluster lies in Orion, and its 100 members lie within a 10' area. Because the individual stars are quite faint, the cluster must be carefully picked out from the background Milky Way.
(Lick Obs Bul, Vol 14, No. 420) gives the diameter as 8' and the class as 4 2 r. He notes: "Described in the NGC as a nebula. Photograph with Crossley Reflector (30m, H D Curtis) shows a well resolved thin but rich cluster of exclusively faint stars (15-18 mag)."
by Jim Lucyk: Deep Sky #5 Wi83 p13.
The RNGC (Sulentic and Tifft 1973) notes that this is a 11.0 mag open cluster.
Coe, using a 13" f/5.6, notes: " Pretty bright, pretty small, very rich, very compressed, 46 stars counted at 135X. Averted vision shows a mottled backround of stars in a very rich Milky Way field."
Alldays (22.50S, 20.12E, 770m).
12-inch f/10 SCT (95x, 218x)
Very faint small condensation with faint stars towards the middle with just a few brighter stars extended slightly further north, which made the size around 10'.
