The Coronado PST state-of-the-art patented technology to provide superb views of both Solar surface detail and prominences. Sub angstrom H-A systems have long been cost prohibitive for the amateur. Designs other than the Coronado are difficult to use because of temperature and F-Ratio requirements. Not only does the Coronado PST solar telescope have a bandpass of and lt;1.0 angstrom (the double-stacked PST has a bandpass of and lt;0.5) but it is also thermally stable and requires no more time to operate than putting in a eyepiece and adjusting the focus. Safe solar observing in H-alpha for a fraction the cost of other solal filter systems is now a reality! The Coronado PST represents the same technology and quality that goes into a SolarMax series telescope, but with a few unique design characteristics that allow us to offer it for less than some premium eyepieces. The Coronado Personal Solar Telescope will show you prominences, active regions, filaments, as well as other surface details. The Coronado PST telescope is made from milled aluminum.
