NGC2264_Hubble_2017_12_8

This was a fairly tough object to process. I took this over 2 nights (7th & 8th Dec) with the moon up and between 70-80% illumination which did affect the subs especially the Oiii. I was going to rotate this but I think it looks better on its side.

 

Note:-

1. I add the Ha stars back in near the end of the process, given me smaller stars and no colour Halo's....

2. This is not true Hubble as it only made up of Ha & Oiii data

 

Information:-

NGC 2264 designation refers to both the Christmas Tree Cluster and the Cone Nebula. The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and the dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264.The nebula is located about 2,700 light-years away from Earth.
