Adding some RGB from my SQM 19 backyard to the Ha data I already had.

I tried various recipes in Pixinsight but not really were doing what I wanted.

Instead I just blended in Photoshop and then did lots of "making sausage" type of processing to get this.

I'm not sure I love it but it is interesting looking and different than just a monochrome image. Certainly nicer to look at than the RGB data I collected from my light polluted backyard!
