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 <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 allow us to offer it for less than some premium eyepieces.
The PST will show you prominences, active regions, filaments, as well as other Solar details – at <1.0 angstrom it will not reveal as much surface detail as the SolarMax series telescopes and filters but it certainly doesn’t disappoint.
The Etalon filters at the heart of Coronado telescopes are extremely fragile. The hard carry case will protect your investment for years to come.
