Wanted to experiment with the H-alpha LS50T etalon which Marie let me use.  However, I could not get it in focus with my Stellarvue 80mm.  So I resorted back to the PST-CaK and was able to make my full disc image of the sun and some closeups using a 1/2″ extension ring and a Meade 140 2x barlow.  will try some more next time the sun is out.
