Looks like this was started in 2019 so we are running about 1000 images/year. These are popular for being so obscure. Gary Imm now even has a book on them….
Up to 6000 Sh2 Images
In the imaging era, Sharpless is the new Messier. Some day we’ll have Sh-2 marathons at remote star parties 😇

I’ve imaged 94 SH2 targets. They’re getting smaller and fainter.
Well most of us live under light polluted skies, HII emission nebula are some of the only targets were building signal is fairly easy.
Thanks for kicking this off, Jerry! You are the godfather of today’s Sharpless movement!

Yes, this is how I started off with them as I had few choices in Silicon Valley. That being said they are remarkably varied,

That’s very true. HII emission nebulae are definitely more forgiving under light-polluted skies since narrowband filters can isolate the emission lines and help cut through the glow. They’re a great target choice when dark skies aren’t an option.

These are also great targets for night vision visual astronomers out there (with narrowband filters)!
