This is an interesting object, even a very interesting one.
In my experience, it is best photographed in Ha and Oiii.
The final image is R-Ha G-Oiii B-Oiii.

Yes, it could have been done without SII, although it's definitely present there. Since switching to monochrome, I've been adding this SII wherever possible.

There's very little sulfur, so it's pointless to shoot it; it's better to accumulate H and O to reduce noise.

Don't you want to join our Snail lovers' regiment? life_is_good is my VK account and miroshn11 is another person's. We'll create a group chat. Let's try to combine our results to get more.

No, I definitely don't consider myself a planetary imager, and I'm not on VK either. If you're interested, I can share the stacks for you to dig into. But the material is so-so—poor seeing, and I finished shooting when it was only about 15 degrees above the horizon.
