Hi, I've got a lunt80 single stack, and it's a very satisfying thing to use. Add a decent monochrome video camera and a good barlow, and the system produces some pretty spectacular images. I did plenty of research at the time and the 80mm Lunt was my choice, but I'm sure things have moved on in a year. One thing that surprised me was that a dedicated H-alpha scope is comparable in price to H-alpha filters for existing scopes, and there's a lot less mucking about.
You can always upgrade to double stack, but after 6 months with the thing I'm still not desperate to do it. Beware of very long delivery times....
cheers,
Andrew.
