NGC 2245 is a reflection nebula in Monoceros
NGC 2245 (LBN 904) is a reflection nebula in the constellation Monoceros . It shines at magnitude 11.0 and spans 2′. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in February.
Nebula: a cloud of gas and dust. Emission nebulae glow on their own, lit by ultraviolet light from hot young stars; reflection nebulae shine by starlight scattered from dust; dark nebulae block the light behind them.
