This image combines data from two optical systems and frames the famous Cats Paw Nebula in Scorpius.
As already discussed, this nebula appears a deep red colour due to significant amounts of intervening dust between us and the nebula.
Although subtle, there
was some colour variation present in the RGB data too which I tried to showcase as well
Details of the two data sets can be found under the image:
