Lunt Solar Systems Filters H-alpha LS50FHa/B600d2 (15921)

The LS50 Etalon filter is designed to provide high-contrast solar views, with a bandpass of less than 0.70 Angstroms. This allows for excellent detail on both the solar surface and the edge features such as prominences. For those seeking even higher resolution for visual observation or imaging, an additional etalon can be added to reduce the bandpass to approximately 0.50 Angstroms, depending on the specific telescope used. This filter is suitable for telescopes with a focal length of less than 540mm and is built for easy integration and safe transport.
