Product description

50mm H-alpha solar filter system with B3400 blocking filter, for front mounting at telescopes with 2" focuser, and up to 3060mm focal length.

The LS50FHa H-alpha Etalon filter system with 50mm aperture (no central obstruction) for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).
The system includes the B3400 blocking filter, which is usable for telescopes up to 3060mm focal length. The blocking filter is installed in a straight extension tube for 2" focuser. This extension tube is equipped with a reception for 2" eyepieces and a adapter for 1.25" eyepieces.

Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.
