This was my first photo with a new 115mm refractor, taken as an experiment before I even saw the challenge. It consists of 400 separate RAW photos taken over a 40 minute span and stacked together in Pixinsight. I kept the individual exposures down to 6 seconds each due to lousy polar alignment with an old mount, but I'm pretty happy with the result... especially after standing out in an open field by myself at midnight as fisher cats screeched in the dark. A large black bear and cub were spotted here a few days later.

EDIT: I'd like to thank the academy for my worst finish in 12 years on a challenge topic that's my specialty.
