Description

I had to target one of the "remaining" nebulas before galaxy season begins, not many are still visible from my spot in the yard. Since I did not have so far a decent SHO image of Sh2-292 I went for it, even with the almost full moon close by, I just had to do it 😊. I did not expect the greatest quality, was kind of surprised though how well it turned out, even the OIII channel.
For me the nebula definitely resembles the most famous dinosaur of all, the "lovely" T-Rex. And since birds are seen as one of the descendants of the dinosaurs, it makes actually "sense" to call the wide field view the Seagull nebula.
For the blending of the RGB stars I used the mechanism that my good friend Mike Feigenbaum suggested (thank you so much for this Mike!!), watching the YouTube video of

VisibleDark: Easily combine RGB stars with narrowband in Pixinsight

There was a technique in there that I did not know about so far. I actually have to slap myself on the head about it since I tried to find this on my own and never got the correct idea. This definitely made a big difference, and I will try to use this technique with other stuff as well.
