IC 2169 / IC 447 Widefield
Dreyer's Nebula
In the constellation Monoceros, west of the Cone Nebula and the Christmas Tree Cluster IC 2169 / IC447 can be found, a true gem of a reflection nebula. Next to IC447, the smaller reflection nebulae IC 446, NGC 2245 & 2247 can also be seen. The entire region belongs to the "Monoceros R1 Complex" (Mon R1), an active star-forming region located approximately 2,500 light-years away. In the area of the gas cloud on the left side of the image, the star cluster NGC 2259 and some LDNs and LBNs are also present.
