Well, mine has selective processing too...I have been using the technique for blending Ha described by Tony Hallas in the link you sent earlier.

Gregg,

This is fantastic. This is the deepest Sh2-223 I've found. I went back and looked at mine and it doesn't have any of the stuff 'inside'. You have more than Dean's and I tend to think his have a lot of selective processing.

Subject: [ASEMDigitalSIG] Sh2-223 and visitor

Hi all

Sh2-223 is a large but faint emission nebula in Auriga; when I started imaging it I noticed that comet c2017 T2 PanSTARRS was going to pass in front of it on November 18 and 19.
