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.
