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.
