Lunt LS50FHA Etalon Filter

By adding this double-stack etalon system, the full-width at half-maximum (FWHM) of an existing H-Alpha telescope can be reduced to approximately <0.55 angstrom. This makes more details on the Sun visible and significantly increases contrast. The filter´s mounting thread is M90x1.

The filter allows you to convert an existing refractor into an H-alpha telescope. You will also need a blocking filter. Blocking filters are linked in the accessories section. When the filter is used only with an optional blocking filter, the FWHM <0.75 angstrom.
