This Ca-K module can be used at the LS130THa/B1200 and LS130THa/B1800 telescopes to observe the Sun also in the Calcium-K line. At the LS130THa/B3400 additionally the conversion kit for the LS130THa is required (item number 0551696).
You can use this Ca-K module with your LS130THa telescope to observe and photograph the Sun 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 LS130THa H-Alpha telescope. If the H-alpha Etalon unit is removed from the LS130THa, the Ca-K module is simply inserted into the focuser instead of the blocking-filter.
The additional conversion kit 0551696 is necessary at the LS130THa/B3400, because at this telescope the blocking filter is fix installed inside the focuser.
For human eyes, the calcium-K light is just at the limit of the visible range. Many people have problems 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.
