The Calcium-K module transforms your normal astronomical telescope into a Ca-K solar telescope. It will be very easy: Put the Ca-K module into the 2" focuser of your telescope, and you are ready for solar observing in the light of the Calcium-K wavelength.

Internal narrowband filters allow for a <2.4 Ångström bandwidth. The Ca-K wavelength is at the edge of the visible light spectrum for human eyes, so for many people visual observing is difficult. However, all details could be captured photographically. Therefore the Ca-K Module is optimized primarily for imaging.

For telescopes up to 102 mm aperture and up to 1800 mm focal length. For imaging it will be better to use a bigger Ca-K module.
