Siebert 1.3X Optical Corrector

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.
