Calcium-K module, for using normal astronomical telescopes up to 100mm aperture and up to 540mm focal length as Ca-K solar telescopes.

This 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 Angstrom 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 100mm aperture and up to 540mm focal length. For imaging it will be better to use a bigger Ca-K module.

The Ca-K module is in a 90° star diagonal or a straight through extension tube, for 2" focuser on the telescope side and with T2 connection and for 1.25" eyepieces on the eyepiece side.
