It's worth the cost

when my PST came back from Coronado after rusty objective replacement it was too bright and ghosty. Simplest soution was to add the double stack. Now it shows prom and surface detail w/out being too bright visually.

This is the only method of double stacking your PST for a more narrow bandpass -0.6 Angstrom - this will dramatically increased the amount of surface detail you can see with your P.S.T.
