- B600 Blocking Filter for 2" focuser in a star diagonal
The LS100 Hydrogen-alpha filter system with 100mm aperture integrally tuned etalon for use on any refractor and many other telescopes. Because the LS100 has an estimated bandwidth of <0.7 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 available. The blocking filter is installed in a 90° star diagonal for 2" focusers. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.
Adding an optional Double-Stack etalon system will reduce the bandwidth to <0.5 Angstrom.
