Description

This is a combination of more recent data taken with my ASI 183 and previous data with the ASI 294 from one of my earlier images: https://www.astrobin.com/b07ev1/B/

As part of the learning curve discovered that AstropixelProcessor has no issue combining the data.

I'm fairly happy as this has improved the target a bit more, along with a small improvement in my image processing skill.
