For sale is a fully functioning Stage 2 PST mod.

It comes with
1 x 100mm Lunt energy rejection filter
1 x Stellarvue 102mm f/11 Achromatic Refractor "Planet Killer"
1 x PST etalon
1 x Astro Optik Kohler and custom adapters for ERF and etalon
1 x 5mm Coronado blocking filter
1 x stock focuser for night time use

I payed a local machinist to create the custom housing for the ERF as well as the aluminum adapter to hold the etalon.

This is a great way to get a PST mod. I did upgrade so I have no more use for this.

The etalon is too finicky for my tastes but the picture shows what kind of views you can expect to get.
