First "recorded" successful Lunt60 mod

[Merlin66]

I'm pleased to report that our six months of R&D has final met with success!
Following the establishment of the "majic" 200mm distance for the PST etalon, we've now done the same for the Lunt 60 internal etalon filter assembly.
The trial mod involved a 150 f8 as a donor....
The early results are VERY impressive...
full details to follow..
