LUNT LS50FHa1/B3400
H-alpha Single Pass Front Mount Etalon System for telescopes with 2" focuser and up to 3060mm 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 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.
