Re: PST modification questions
Aboy,
Modding a PST is relatively straight forward. You seem to already have the ERF and a BF15 blocking filter.
Using the objective SM40 etalon is more complex and needs additional optics.
Drop me an email and I'll send you the PST mod write-up.
(Actually lost and alone in the Scottish highlands at the moment!)
