Double-stack filter for LS50THa telescopes. The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". The smaller bandwidth increases the contrast and detail visible on the Sun's Chromosphere and within Prominences.
This filter is designed specifically for the LS50Tha Telescope. Use of it then reduces the bandwidth to <0.55 Angstrom. It has a thread which attaches directly to the front of the LS50 Telescope
