Somewhere in the World there’s a clear night! In this case it was in Chile.

This is a pro dataset (LRGB) taken with the Telescope Live remote telescope, ASA500N and FLI PL16803 CCD camera in Chile. 

NGC 2264 is an H II region in the constellation of Monoceros. Within it is The Christmas Tree Cluster  – a young open cluster. NGC 2264 is currently an active star forming region.

The Cone Nebula lies in the southern part of NGC 2264. Stars are forming in this gigantic dust pillar.

William Herschel discovered the cluster in 1784, the nebula in 1785.

The above image is comprised of luminance data as well as red, green and blue data. Also known as and shortened to “LRGB”.  The luminance component provides brightness and details while the seperate colour channels when combined produces the colour you see in the image.

I processed the data in PixInsight. The data from Telescope Live is provided calibrated (darks, flats applied already) but needs some work to be done in order to arrive at the final image.
