Description

Bit of a challenge since it was the shortest night of the year and I wanted to see if I could snap something. I tried for the cocoon using a high gain approach with short exposures. It sacrifices some dynamic range but with only half an hour on each of the LRGB filters, and just 15mins on HA, worked out OK I think.
