H-alpha Single Pass Front Mount Etalon System for telescopes with 2" focuser and up to 540mm focal length. A filter system to convert your existing astronomical refractor telescope to a professional solar telescope...

Includes:

  • LS50FHa Main Filter
  • Aluminium Transport case
  • B600 Blocking Filter for 2" focuser in a star diagonal

The LS50 Hydrogen-alpha filter system with 50mm aperture (no central obstruction) integrally tuned etalon for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom, it is capable of providing high contrast views of both surface and edge detail.
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 approximately <0.55 Angstrom.
