The PST is the latest innovation from Coronado. This little telescope is another step toward Coronado's goal of making it possible for everyone to "Experience the Sun our way". 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 PST have a bandpass of less than 1.0 angstrom, but it is also thermally stable and requires no more time to operate than putting in a eyepiece and adjusting the focus. The PST represents the same technology and quality that goes into a SolarMax series telescope but with a few unique design characteristics that allows them to offer it for less than some premium eyepieces.
The PST will show you prominences, active regions, filaments, as well as other surface details - at less than 1.0 angstrom it will not reveal as much surface detail as the SolarMax series telescope and filters but it certainly doesn't disappoint. The PST is made from milled aluminium, not plastic! The P.S.T. comes with a built in Sol Ranger for easy alignment, a 20mm Kellner eyepiece, and a re-usable box with dye cut foam for safe storage.Optional accessories include a hard travel case, MALTA tabletop mount, CEMAX series eyepieces, and SolarMax 40 for double stacking and narrowing the bandpass. (To add a SolarMax 40 you will require the T-Max 40 for attaching the unit directly to the PST).
