This Calcium K module will transform your LS130THa into a high resolution Ca-K solar telescope. Simply replace the standard diagonal / blocking filter with the Ca-K module and you are ready for solar observing in the light of the Calcium-K wavelength. Note this version the LS130 CaK module is only suitable for use with the B1200/B1800 versions of the LS130THa. The B3400 version requires an additional fitting kit.
Internal narrowband filters allow for a <2.4 Angstrom bandwidth at 393nm. The Ca-K wavelength is at the edge of the visible light spectrum for human eyes, so for many people visual observing is difficult. Therefore the Ca-K Module is optimized primarily for imaging which will yield the best results. A Calcium-K module like this will allow capture of high contrast surface detail and also prominences.
The Ca-K module is a diagonal an supplied with 2" and 1.25" clamp fittings.
Results with the filter can be further enhanced by adding the Baader K-Line filter which will have the effect of increasing contrast still further.
