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. The filter threads directly onto the LS40THa telescopes.

FEATURES
  • Aperture: 40 mm
  • Bandwidth: <0.55 Angstrom
  • Tuning: mechanical tilt-tuning
  • Housing diameter:
  • Length:
  • Weight:
  • Front thread:
  • Rear thread:
  • only usable together with a LS40THa telescope!
