Description |
Another very active part of our
galaxy. The open cluster is a fine bright group of about 30 stars
called the Christmas Tree by L.S. Copeland because of its shape. There is
a good deal of scattered emission nebulosity extending south towards
the Cone Nebula (top). The brightest star in this 76 x 113 arcmin field is
15 Mon and to its left (west) is the Fox Fur nebula. Here
is a color rendition. |
