Lunt LS6CaKMDs2 Ca-K Solar Filter Extension Tube

Lunt LS6CaKMDs2 Ca-K Solar Filter Extension Tube

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 challenging at this wavelenght. However, significant details can be captured photographically. Therefore, we recommend the Ca-K Module is primarily for imaging purposes.

This module is recommended for telescopes up to 100mm aperture and up to 540mm focal length.

The Ca-K module is in a straight extension tube, for fitting in 2" focusers on the telescope side and comes with T2 connection and for 1.25" eyepieces on the eyepiece side.
