Description

After the (relative) success of my experiment with the dual narrowband filter here https://www.astrobin.com/azdjcb, I thought I might try one a bigger, grander target.

Well, after piling on more exposure time than I have ever used on any target before, I am still a bit underwhelmed. The star-forming regions do pop nicely, but the galaxy structure is almost not there at all. The light pollution (expecially from the moon) certainly didn't help.
