LUNT LS50FHa

50mm H-alpha double-stack solar filter, for all LS50FHa filter-systems and LS60THa/LS60MT telescopes.

Double-Stack Etalon for all LS50FHa filters and LS60THa telescopes. Adding this additional Double-Stack etalon system will reduce the bandwidth to ~<0.55 Angstrom (dependant upon used telescope). So you will have much more contrast and more details on the sun will be visible.

Technical data:

  • Aperture: 50 mm
  • No central obstruction
  • Bandwidth double stacked: <0,55 Angstrom
  • Tuning: tiltable Etalon
  • Housing diameter: 95 mm
  • Length: 73 mm
  • Front thread: M90x1 female thread
  • Rear thread: M90x1 male thread
  • Weight: 0.7 kg

ATTENTION: Without Blocking Filter! Only for use as double-stack filter, or together with a additional available blocking filter!

If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is <0.75 Angstrom.
