NGC 1858 = ESO 056-SC074 05 09 56 -68 54.0 18" (7/10/05 - Magellan Observatory, Australia): third of three bright objects in a NW to SE string with N1850 and N1854/55. This is a large and very unusual cluster with nebulosity. There is a bright knot attached near the NW edge, ~15"-20" in diameter. This knot responds very well to a UHC filter at 76x (27 Panoptic). An obvious elongated patch of nebulous haze curves to the SE with several mag 13 stars involved with the glow and extended N-S. Overall, the size of the cluster/nebulosity extends to 3.5'x2'. Located 4.5' SE of N1854. | |||
