This is NGC 2244 et. al., aka, the Rosette Nebula in the constellation of Monoceros. The catalog numbers of this object are in dispute (cf Haluk Akcam's analysis), though most seem to agree that NGC 2244 refers to the Open Cluster of stars in the center of the nebula, and NGC 2246 et. al. refer to the nebula itself.
The Rosette Nebula is extremely faint, so I upped the individual exposures (8min) and cranked the ISO (1600) in order to better resolve the nebula. Close inspection reveals that the faintest traces of nebulosity are still below the read-noise floor of the camera. The cost of these long exposures/high ISOs is, of course, a washout of the color in the brightest stars. A worthwhile tradeoff IMO.
A higher-resolution image is also available. North is up.
