Coronado PST CaK Solar Telescope

Coronado P.S.T. CaK is a truly remarkable telescope linking two of the most recent technological breakthroughs. By combining the optical design of the price friendly P.S.T. with the Calcium K line filters of the CaK 70 telescope Coronado 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.

These are just some of the shots that people have captured with this telescope
