Description

Abell 84 is a faint planetary nebula in the constellation Cassiopeia. It is rarely imaged - I'm baffled as to why. This was an experiment to see how much structural detail I could tease out of this target as I couldn't find much in other online images. All data capture was done around full moon. I went deep to get good quality data despite the lunar presence and used drizzle x2 for the first time to increase image resolution.
