This etalon sun filter is compatible with all LS50FHa filter systems and LS60THa telescopes of Lunt Solar Systems.

By adding this etalon system allows the FWHM reduce to ~ <0.55 Angstrom (dependent upon scope). Thus the contrast is increased significantly on the solar surface, which more details on the sun are visible.

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

  • Opening: 50mm
  • Tuning: tiltable Etalon
  • Threaded front: M90x1 internal thread, thread behind: M90x1 male thread

Please note: only to use as a double-stack filters or together with an additional available blocking filter.
