With BRESSER, you can enjoy a smooth introduction to the vast world of astronomy. Our detailed information ("Telescope Guide") provides valuable tips for beginners—but even experienced astronomers can use the information we provide (e.g., tables for the geographical latitude of all major world cities) as a reference.

The LS50FHa H-alpha Etalon filter system with 50mm aperture (no central obstruction) for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).
The system includes the B1200 blocking filter, which is usable for telescopes up to 1080mm 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 ~<0.55 Angstrom.
