NGC 2264 is also known as the Christmas Tree. The Cone Nebula is at the lower edge of the image. The Foxfur Nebula can also be seen just to the right of the bright star at the top of the image. The RGB exposures were of the same length to accomodate atmospheric refraction as the object is at a low altitude from my location.
