A filter system to convert your existing astronomical refractor telescope to a professional solar telescope...

  • LS60FHa Main Filter

The LS60 Hydrogen-alpha filter system with 60mm aperture (no central obstruction) integrally tuned etalon for use on any refractor and many other telescopes. Because the LS60FHa has an estimated bandwidth of <0.7 Angstrom it is capable to providing high contrast views of both surface and edge detail.
The system includes the B1200 blocking filter, which is usable for telescopes up to 1080mm 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 approximately <0.5 Angstrom.
