Corwin's Notes
=====
NGC 4052. There is nothing at JH's place, but 1 minute of time west is a
cluster, about 9 arcmin by 9 arcmin, that fits his description ("Cluster VII
class; loose and scattered, but pretty rich."). I have no doubt that this is
his intended object.
This is one of the very few that Brian missed; his position (12 00 00,
-63 13.6; J2000) is for a random star field two minutes of time preceding the
cluster. His estimated diameter, however, 7.5 arcmin is roughly correct. Is
the RA perhaps a typo?
Steve's Notes
=====
NGC 4052
13.1" (2/20/04 - Costa Rica): this cluster is located in the field, just 10' NW of mag 4.3 Theta 1 and 15' W of mag 4.7 Theta 2 Crucis in the SW portion of the constellation! At 105x, ~60 stars mag 10 and fainter are mostly scattered in a 9' diameter. More striking, though, is a dense 3' subgroup of mostly mag 12-13 stars on the SE end of the cluster over a background of haze from unresolved stars. A neat string of six stars oriented WNW-ESE is located on the south end with a brighter mag 9.5 star about 2.5' further west.
