I was wondering if anyone had tred triple stacking a PST - ie putting a pair of SM40 etalons on the end?
Now I expect that the image is going to become horrendously dim, with the 2 extra ERFs on the external SM40 etalons, however, if one removed the ERFs then could bring image brightness up to acceptable levels?
I'd try it myself however the PST at school is out on loan to students, and they don't seem too keen to bring it back in a hurry!
