Comment |
North is to the
top.
Object identification,
in the constellation of Lacerta, is very confusing and
contradictory. The light brown molecular cloud is LBN 437. The red
emission nebula is the northern portion of Sh2-126. There are
additional bright nebulae, as cataloged by Beverly Lynds.
Unfortunately, the data are confusing and the objects appear to be
overlapping.
