LUNT LS50FHa
50mm H-alpha double-stack solar filter, for all LS50FHa filter-systems and LS60THa/LS60MT telescopes.
Double-Stack Etalon for all LS50FHa filters and LS60THa telescopes. Adding this additional Double-Stack etalon system will reduce the bandwidth to ~<0.55 Angstrom (dependant upon used telescope). So you will have much more contrast and more details on the sun will be visible.

- Bandwidth double stacked: <0,55 Angstrom
- Tuning: tiltable Etalon
- Housing diameter: 95 mm
