I've posted a Ha narrowband image of this object (NGC2264) previously but this full "Hubble palette" SII/Ha/OIII image brings out some of the real detail in the nebula. It presents itself well at this tme of year which is always appropriate, as it's commonly known as the "Christmas Tree Cluster" or the "Mother and Child" nebula. The nebula is around 2500 light years away in the constellation of Monoceros and is formed from dust reacting to the energetic light and gas being expelled from the hot young stars embedded within.

Limited clear sky time means the image (which is 3 hours worth sub frames in total) is very noisy and it's taken a lot of processing even to get it to this stage.
