Lunt Calcium (Ca-K) filters

Not only in the H-alpha, also in the Calcium-K wavelength the sun will show you many details. But for human eyes it is difficult to see this wavelength. Therefore, the Ca-K telescopes and modules from Lunt Solar Systems are optimized primarily for photography.

More about the product

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 1620mm 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, for 2" focuser on the telescope side and with T2 connection and for 1.25" eyepieces on the eyepiece side.
