Description

Hadn't imaged this in a number of years so thought I'd see what I could do with it this time. Only got 1 1/2 hours on it but amazed at how clean the image was for the short integration. Hopefully will continue with NB when skies clear again and the moon moves on a bit!

Was able to get OIII and SII this weekend!
