Product description

This double-stack etalon solar filter is compatible with all LS50FHa filter systems and LS60THa / LS60MT telescopes from Lunt Solar Systems.

By adding this double-stack Etalon system, the half-width can be reduced to approximately <0.55 Angstrom (depending on the telescope used). This significantly increases the contrast on the sun's surface, allowing more details on the sun to be seen.

If the filter is used single-stacked with an optional blocking filter, the half-width is <0.75 Angstrom.
