The Coronado Personal Solar Telescope (PST) is a wonderful way to look at the sun in Hydrogen-alpha, and has produced a legion of new "solar addicts" in the short time since its release. One of the limitations of this scope compared to Coronado's higher end products was its inability to come to focus with binoviewers, even with fairly significant Barlowing.
Saturday Jim Richberg and I got together with our Coronado Personal Solar Telescopes (PSTs). There were two tests we wanted to test: a side by side comparison of the two PSTs and to conduct a PST eyepiece shootout.
You can’t go to a star party these days without bumping into one of Coronado’s Hydrogen Alpha (Ha) Filters. All it takes is one look and your hooked. Seeing the solar chromosphere come alive in Ha light is thrilling. I have had the opportunity to look through and compare the 40mm, 60mm and 90mm versions as well as a stacked 40mm and a stacked 90mm. When it came time to purchase one, I bought the 60mm.
