Lunt LS50C H-alpha Double-stack Filter for LS50THa
Lunt LS50C H-alpha double-stack filter for LS50THa - Double-stack filter for LS50THa telescopes. The bandwidth of H-alpha systems can be reduced by so-called "double-stacking".

Therefore Lunt Solar Systems has especially designed this LS50C double-stack filter in compact housing.
