Lunt LS6CaKMDd2 Ca-K 90° Diagonal

Lunt LS6CaKMDd2 Ca-K 90° Diagonal

Description
The Lunt LS6CaKMDd2 is a fully integrated Ca-K narrowband filter module built into a 90° star diagonal. It converts a conventional refractor into a Ca-K solar telescope without needing any additional filters or accessories.

The Ca-K wavelength allows detailed imaging of faculae and solar activity regions, though it lies near the visual spectrum limit and is hard to perceive visually. For this reason, it is primarily recommended for solar photography with sensitive cameras.

This model is designed for refractors up to 100 mm aperture and 540 mm focal length. It features a 2" input, 1.25" eyepiece holder, and a T2 camera thread.
