Object:	NGC 2264: Cone Nebula and Vicinity in Monoceros RA = 6 hrs 41 min; Dec = 9 deg 53 min
Date & Site:	Imaged on 1/10/14 and 1/21/14; Runningman Observatory, Carlsbad, CA Clear; very good seeing; very good transparency Temperatures in low 50s
Equipment:	Telescope: Takahaski FSQ106 Refractor (540mm fl f/5) Mount: Losmandy G-11 with Gemini Camera: ST-10XME; CFW10 with 3 nm Astrodon filters; Autoguided with a 100 mm guidescope and SBIG guide camera
Notes:	Exposures and filters: 3 hrs of Ha; and 1.25 hr each of OIII and SII (15 min subexposures) for a total of 5.5 hrs. Color mapped using the Hubble Palette assigning Hydrogen alpha to Green; doubly ionized oxygen to blue and ionized sulfur to red FOV =96 x 65 arc minutes The Cone Nebula (located at the left edge of this image) is an HII emission region in Monoceros. The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust blocking a faint background emission nebula. The cone itself is approximately seven light-years long. This wide-field image also shows the Christmas Tree nebula and the Fox Fur nebula as you view from left to right.
