Product Details

Lunt 50mm H-alpha Solar Filter System - LS50FHa2/B1800

H-alpha Single Pass Front Mount Etalon System for telescopes with 2" focuser and up to 1620mm focal lentgh.

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 LS50 has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both surface and edge detail.

The system includes the B1800 blocking filter, which is usable for telescopes up to 1620mm 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 ~<0.55 Angstrom.
