LUNT LS40FHa H-alpha double-stack filter for LS40THa

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. FEATURES Aperture: 40 mm Bandwidth: <0.55 Angstrom Tuning: mechanical tilt-tuning Housing diameter: 70mm Length: 60mm Weight: 0,3kg only usable together with a LS40THa telescope!
