LUNT LS100FHa/B600d2 H-alpha solar filter

100mm H-alpha solar filter system with B600 blocking filter, for front mounting at telescopes with 2" focuser, and up to 540mm focal length.

The LS100FHa H-alpha Etalon filter system with 100mm aperture for use on any refractor and many other telescopes. Because the LS100FHa has an estimated bandwidth of <0.7 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).
The system includes the B600 blocking filter, which is usable for telescopes up to 540mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 2" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.

Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.5 Angstrom.
