Product description
50mm H-alpha double-stack solar filter, for all LS50FHa filter-systems and LS60THa/LS60MT telescopes

This double-stack Etalon is compatible to all Lunt Solar Systems LS50FHa filter-systems and LS60THa / LS60MT telescopes. Adding this additional double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom (dependent upon used telescope). So you will have much more contrast and more details on the sun will be visible.

Without blocking filter! Only for use as double-stack filter, or together with a additional available blocking filter. If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is <0.75 Angstrom.
