Q&A: Galaxies, Galaxy Clusters, AGN, and Quasars

Q:
I need an image of the constellation Orion that also shows which nebula (or cluster, or whatever) is where. For example, I can find lots of images of the Orion Nebula Cluster, but nothing that shows me where it is in relation to the rest of the entire constellation?

A:
Try the following web site. http://www.seds.org/Maps/Stars_en/Fig/orion.html Better still, consult Burnham's Celestial Handbook, Vol. 2, p. 1324, where you will find a description of the various stars in Orion. In particular, Burnham says that "Half a degree north of the Great Nebula is the star 42 Orionis surrounded by the nebulosity NGC 1977....Another 25 minutes to the north is the scattered grouping of 8th to 10th magnitude stars designated NGC 1981." .
