Description

Looking for input from the collective Astrobin mind.  I imaged Messier 101 on May 1st of this year.  This is before I had heard anything about the discovery of a new super nova in the galaxy.  Can anyone tell me if this is pre nova.  I also have an image from 5-16-2023 which is not very good, but I still don't think I see a nova in that image as well.  Thanks for any comments.
