NGC2264 and The Cone Nebula in Monoceros


(Click on image for full size version)


Description: The cone nebula at the left is a very large cloud of Hydrogen and particles associated with a loose open cluster NGC2226, located at the tip of the cone.  Farther to the right is NGC2264, another open cluster about 2,700 light years distant.  The nebulosity is a combination of red Hydrogen emission and blue reflection from the cluster.  Some dark dust lanes are also visible.  The bright star at the far right is S Monocerotis.
Exposure Data: 1/7/2002 LRGB: 17x3m, 6x3m, 6x3m, 6x3m. RGB binned 2x2. -25°C, 2.65 arc-sec./pixel.
Processing: Acquired in CCDSoft, reduced, aligned and combined in Mira, RGB combine in Maxim, L+RGB combine, curves, levels, bloom repair and other adjustments in Photoshop.
Optical System: TV-140 5.5” f/5 APO refractor, ST-8E NABG/CFW-8A CCD camera, AP900GTO mount.
Comments: Used Rob Gendler’s LLRGB layering to enhance the color data. It made a significant improvement on this originally too noisy data. Although still too noisy, it was amazing to watch the color data “develop” as Rob’s technique was applied.
