Coronado PST

The Personal Solar Telescope

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.

PST-Cak Product Description

Coronado P.S.T. CaK is a truly remarkable telescope linking two of our most recent technological breakthroughs. By combining the optical design of the price friendly P.S.T. with the Calcium K line filters of our CaK 70 telescope we are again making solar discovery a real and attainable aspect of Astronomy.
The unique CaK filter isolates a layer of the Sun that is below and slightly cooler than the layer viewed with a Coronado Hydrogen Alpha filter. The transmission line is centered at 393.4 nanometers and is isolated using thermally stable interference filters. Given that this telescope has a much smaller aperture than its bigger brother, the CaK 70 telescope, you can anticipate a drop in resolution but not in contrast, safety, or quality. The magnificent super granulation cells that gather and strengthen in this layer of the Chromosphere may not be visible to all, as most humans eyes through the process of aging are not particularly sensitive to this wavelength. The primary purpose of any CaK instrument is for imaging.
**Due to the short wavelength of the CaK line some people may have difficulty seeing every detail. However, imaging at this wavelength using standard cameras and webcams is relatively easy and produces images that are readily viewable**.
