Lunt LS18CaKMDs2 Ca-K Extension Tube
Description
The Lunt LS18CaKMDs2 is a complete solar filter module using the Calcium-K spectral line. Built into a 2" straight extension tube, it converts a standard refractor telescope into a professional-grade Ca-K observation instrument.
It supports refractors up to 100 mm aperture and 1620 mm focal length. The narrow <2.4 Å bandwidth reveals chromospheric detail such as supergranulation and early solar activity.
The module features a 1.25" eyepiece adapter, a T2 camera thread, and a B1800 internal blocking filter. All required filtering is integrated into the compact housing, making it ideal for advanced imaging.
