Baader imaging filters

[Anne S]

Are the Baader LRGB filters parfocal with their narrowband filters, the Ha, O3 and S2 ones? I have Astronomik LRGB and Baader narrowband in my filterwheel. The narrowband filters need refocusing after LRGB which means I can't include then in an imaging sequence. I haven't managed to get autofocusing working in Maxim dl yet.

I bought the LRGB first for a previous camera and then couldn't afford the 3nm Astronomik narrowband when I upgraded.

As far as I am aware the Baader LRGB and standard NB filters are all 2mm, so theoretically par focal.  I certainly don't have to re-focus between my LRGB and 7nm Ha filter.

Will also depend on what scope you are using. They certainly weren't on my mine.

I've got an Altair Wave 102 triplet refractor that I use most of the time, 715 mm.
