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.


  • 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!

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