Description

While the moon was still over 90% illuminated, I decided to look for another narrowband target and found the Owl nebula. I captured six hours in Ha and OIII and added it on to 10.1 hours of archived data I had from last year.

It wasn't very big so I drizzled it and did come major cropping to bring it in closer.
