Lunt LS50C H-Alpha Double-stack Filter for LS50THa H-Alpha Telescope
The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.
Double-stacking with a bandwidth of only <0.5 Angstrom is also possible at the LS50THa telescopes. Therefore Lunt Solar Systems has especially designed this LS50C double-stack filter in compact housing. The filter threads directly onto the LS50THa telescopes.
- Aperture: 50 mm
- Bandwidth: <0.5 Angstrom
- Tuning: mechanical tilt-tuning
- only usable together with a LS50THa telescope!
