Description

Quick test image after I tried to correct my sensor tilt with the ZWO T2 tilt adapter. The field is not totally flat yet but at least it's much better than what I was used to. Hopefully, I can get there once I dial in the tilt adapter properly :)

I was happy to see these test results after months of struggling with the star shapes.

This was also the first time I ever attempted to image this region of the sky, and the default orientation of my camera worked out surprisingly well to frame these two galaxy groups.
