Each time I clean the hard drive I find old files that have been lost, misplaced and forgotten. This one dates back several years. It was taken with my old filters that had nasty blue halos even on red stars. Not knowing how to deal with them in this image I seem to have filed it in an obscure folder and it was gone. I really should redo this one with far more time and with my new filters that don't have the halo problem. But with this winter's horrid weather that didn't happen. I'll have to go with this salvaged image.
The Cone Nebula is part of a larger nebula involved with a star cluster. The combination is known as NGC 2264. The cluster, most of which is outside this image is sometimes known as the Christmas Tree Cluster due to its shape. The combination is thought to be about 2500 light years away. It is located in the constellation of Monoceros which is a unicorn.
