Cool. I'm thinking of getting an Ha filter for my Jupiter too. I'm wondering how much worse a 36nm one would be.

Thank you! It's hard to say for sure, as it depends on factors like the level of light pollution in your shooting location, etc. But I think it would certainly be better than shooting through two filters, as I do now.

In my opinion, it's not very bright, imho. The transition in the shadows could be defined more sharply. And it's a bit noisy for hydrogen.

Agreed, this is more of an intermediate technical frame without post-processing, to make it easy to compare the difference. I hope to continue with this object later.
