About this image

This data for this image was mostly captured during Feb 2020, starting with some Ha data on 6 Feb with a bright Moon in the sky and was completed on the night of 1/2 March with more Ha data and some luminance, again with a fairly bright Moon around. The RGB data and remaining luminance were captured in a Moonless sky towards the end of Feb.
