Coronado ST 40/400 PST Personal Solar Telescope <0.5Å OTA

 

The PST is the latest innovation from Coronado. This "little" telescope is another step toward our goal of making it possible for everyone to, "Experience the Sun our way."

Sub angstrom H-alpha 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 surface 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.
