| Notes:* | Another case of position/identity confusion ... I shot IC 1848 (as a
open cluster) based on Megastar v5.0.13 position listed above. The
CDS
has a position of 02h 49m 20.9s, +60d 38m 03s, which is to the Northwest
(upper right) in this image, and identifies it as an HII region (among
other things). "Star Clusters", by Brent Archinal
and Steven Hynes, has basically the same positional data as
Megastar, however, in their notes, they conclude "To summarize, IC
1848 is both Cr 32 and Cr 33, a cluster in the western end
of this complex. Cr 34 is a possible (but not proven) cluster in the
eastern end of this complex. Barnard essentially discovered both." They
note that Barnard photographed this region, and noted that the clusters
were 'immersed in a bed of feeble nebulosity'.
The NGC / IC Project has no visual observations for this area, but lists the Contemporary/Current Data as Cluster/nebulosity, 02h 51m 12s, Dec +60d 26m 00s, Class: I 3 p n (Sharpless Classification 3:2:3, 120' diameter) |
