LUNT LS50C H-alpha Double-stack Solar Filter

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 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.

Features:

• Aperture: 50mm
• Bandwidth: &<0.55 Angstrom
• Tuning: mechanical tilt-tuning
• Housing diameter: 85mm
• Front thread: M80x1 female thread
• Rear thread: M80x1 male thread

Only usable together with a LS50THa telescope!

The kit includes:

• LS50C H-alpha double-stack filter
• Instruction manual
