Description

My first Narrowband image. Ran into some challenges trying to match the frame with my existing HA data. But since the new filter-wheel ended up flipping the camera 180 degrees, I ran into rotation issues. Ended up starting over with a fresh set of data just to get a cleaner set.

ToDo: Learn how to cleanly blend data from non-aligned subs without getting the border issues in PixInsight.
