This is a potentially dangerous topic for me. Well, maybe my wallet.
I was idly checking out H-alpha filters other than the usual suspects, and encountered another player in the marketplace:
US Price list
A search here shows an occasional mention of these filters, but very little in the way of discussions about it. I see some discussions about it in the solarchat forum, but still nothing too extensive.
The pricing doesn't appear to be too bad, at least when compared to competing rear etalons.
What's also curious to me is that because I first heard of them through Baader, I was under the impression that they are Europe-based, but based on their website they at least have a US presence.
I'm just curious as to what users of these filters on this forum have to say, how they like them, etc.
