Looking for a PST 40mm front objective lens( blue coating). If you have one left over from a PST mod which you won’t be using and are interested in selling, please PM me with a price.
Thanks.

Still looking for one if anyone has one available.

Stupid question, why just the front, thanks

Hi Jeremy, I bought a used PST which has a rusted front lens( which means the energy rejection filter/ Induced transmission filter has deteriorated. The etalon works fine, I will use the scope in a PST mod, but want the option to use it as a 40mm grab and go Ha setup as well.
