and NGC2158
Open
cluster assemblage in Gemini
Uploaded 3/19/05
There are actually four open clusters
in this field of interest, First, the large open cluster in the
center is M35, a half a degree diameter 5th magnitude gem with
a total near 200 stars. It is 10x closer than the object to its
lower right, NGC2158 an 8.6 magnitude cloud of stars only 5 minutes
in size but containing some very yellow stars. Over to the right
edge are two other objects. Just below center on the right edge
is IC2157, an 8th magnitude sparse cluster. Just above it and
barely a cluster is IC2156. |
