Double-stack filter for LS40THa telescopes.
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 <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing. The filter threads directly onto the LS40THa telescopes.
FEATURES
- Aperture: 40 mm
