NGC-2264

Sedro-Woolley, Wa.

This photo contains various named objects in the constillation Monoceros with celestial north at the left.
The field of view is about 1 X 1.5 degrees, centered at about RA: 6h41m DE:+09°38'.
When rotated to the left 90 degrees the Christmas Tree cluster can be decerned. To the lower right is the cone nebula.
Other named objects are the snowflake cluster and the Fox Fur nebula, though I am not sure where to locate those objects.
The weather and viewing conditions were not very good and will have to try to get more data to reduce the noise levels.
Presently, this is what I have so it is what I will post.
The distance to the nebula is about 2500 light years away. The Cone Nebula was cataloged by Herschel in 1783.
Considering the instruments available at the time the discovery is a testiment to the dark skies of the time. It is too bad that light management of the present day is so poor.
