Lunt 100mm Ha Etalon Filter with B1800 for 1.25" Focuser

Price is based on R7.00/$.

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 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 1.25" 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 ~<0.5 Angstrom.
