The Coronado CaK Personal Solar Telescope is a singular solar telescope that combines the optical design of the price friendly Coronado Personal Solar Telescope (PST) with the Calcium K (CaK) line filters of the Coronado CaK 70 telescope. The unique CaK filter of the Coronado Ca-K PST Telescope 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 Coronado Solarscope has a much smaller aperture than its bigger brother, the Coronado CaK 70 telescope, the resolution is lower but not the 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 but they are visible to any low-end CCD camera. The primary purpose of this telescope is for imaging. This telescope has NO tuning collar, only a focus knob. It comes with a 20 mm Kellner eyepiece. This gives a magnification of 20x, as the scope itself has a focal length of 400mm and it mounts on a standard ¼-inch tripod mounting bolt.
