NGC 2264
Image Information

What do the following things have in common: a cone, the fur of a fox, and a Christmas tree? Answer: they all occur in the constellation of the unicorn (Monoceros). Pictured as a star forming region cataloged as NGC 2264, the complex jumble of cosmic gas and dust is about 2,700 light-years distant and mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dust clouds. Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae. The image spans about 3/4 degree or nearly 1.5 full moons, covering 40 light-years at the distance of NGC 2264. Its cast of cosmic characters includes the Fox Fur Nebula, whose convoluted pelt lies below center, bright variable star S Mon immersed in the blue-tinted haze, and the Cone Nebula near the tree's top. Of course, the stars of NGC 2264 are also known as the Christmas Tree star cluster. The triangular tree shape traced by the stars appears here with its apex at the Cone Nebula and its broader base centered near S Mon.

Note : My image below is considerably smaller in covered area, closer to 3/4 or more of the full moon, so maybe just short of 3/8° field of view.

This image is one of my not so long ones but due to it's bright area seems to do well with a bit less. The luminance data is 12 - 15 minute frames (3 hours) and there are 8 each RGB frames each 15 minutes each (6 hours) with 2 hours red, 2 hours green, and 2 hours blue. Image processed in Pix Insight. Data acquired using ACP Expert and MaxIm 5.24.
