Great photos. It's very interesting to see pure H-beta.

Thanks, I'll try to find them and stack them separately during the week!

Thanks. I'll take a look. Please don't delete it for a couple of days.

I see. Thank you for your time. But... now I'm curious to see the OIII. If it's not too much trouble. My interest isn't just casual. If you noticed, I also try to shoot with a camera lens. And I'm interested in narrowband imaging. So I would really appreciate it.

Please. Here there is oxygen, but in my opinion not all of it, only a part. https://yadi.sk/d/0Fp1OhGPYKZksQ
But overall, I think it will be clear what's what. The images were taken with an open setup and without a microfocuser, so the stars are poor, and there were also initial problems with calibration. Now I could improve the result with the same equipment. I abandoned shooting in H-beta because it almost completely duplicates Ha and also captures a bit of oxygen. The contribution of blue from the H-beta line can be created synthetically by mixing Ha into the blue channel when assembling the pseudo-color image.
