First process of SH2-73. 4 hours exposure selected from Job 1971.

I am pleased to have pulled out this faint nebula as it was a bit of a struggle. There are a number of small galaxies in the field of view that tended to blow out or look very weird if not carefully masked during the stretch.

The bright star to top right is 44 (Pi) Serpens.

I may resubmit the job for additional data as about half the subs had to be rejected.

It also looks good as a square crop keeping the bright star out of the frame.
