LUNT LS50FHa H-alpha double-stack solar filter
LUNT LS50FHa H-alpha double-stack solar filter50mm H-alpha double-stack solar filter, for all LS50FHa filter-systems and LS60THa telescopes.
This double-stack Etalon is compatible to all Lunt Solar Systems LS50FHa filter-systems and LS60THa 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.
