Well, this is a long story:
1. I had empty imaging time so I thought I would do M 38, which was overhead. I noticed that there was a PN nearby in The Sky X (TSX) and said great, wonder what that is?
2. So in TSX is said that 172 +0.1 is also known as Abell 9.
3. Abell 9 was scratched off the list, and I can see why since there is a lot of H-Alpha around there and several Sh2 objects to the right off screen.
Anyway, here it is. I did this previously but this is the context.
I put up the original RGB, which shows nothing, then the destarred HA, where it is prominant, and then the RGB-HA... lost some of the resolution to the object which is in the HA... HA wins.
