LUNT LS18CaKMDs2 Ca-K filter in extension tube

Calcium-K module in straight extension tube, for using normal astronomical telescopes up to 100mm aperture and up to 1620mm focal length as Ca-K solar telescopes.

This Calcium-K module transforms your normal astronomical refractor 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. For refractor 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 straight extension tube, for 2" focuser on the telescope side, and with T2 thread and 1.25" eyepiece connection on the eyepiece side.

All needed filter parts are integrated inside the compact module. There are no additional filters needed.

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.
