Double-stack filter for LS50THa 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 <0.5 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.

Specification:



  • Aperture: 50  mm

  • Bandwidth: <0.5 Angstrom

  • Tuning: mechanical tilt-tuning

  • Housing diameter: 85 mm

  • Length: 70 mm

  • Weight: 0.7 kg

  • Front thread: M80x1 female thread

  • Rear thread: M80x1 male thread

  • only usable together with a LS50THa telescope!
