LUNT Ca-K Filter Module for LS130MT
This Ca-K module can be used on the LS130MT/B1200 and LS130MT/B1800 telescopes to observe the Sun in the calcium-K line as well.

With this Ca-K module you can observe and photograph the sun with your LS130MT telescope not only in H-Alpha, but also in the blue Calcium-K wavelength. Here again completely different phenomena become visible on the sun than in H-Alpha.

This Ca-K module was specially designed for the LS130MT H-Alpha telescope. When the H-Alpha etalon unit is removed, the Ca-K module is simply plugged into the focuser instead of the blocking filter.

The calcium-K light is just at the limit of the visible range for human eyes. Many people have problems here with visual observation. However, this does not apply to photography, where the Ca-K module shows everything the sun has to offer in this wavelength.
Central wavelenght:393,4 nm (Ca K line of Ca II)
Bandwidth:<2,4 Ångström
