LUNT LS60FHa 60mm H-alpha Double Stack Etalon Solar-Filter
Double-Stack Etalon for all LS60FHa filter systems and LS60THa telescopes. Adding this additional Double-Stack etalon system will reduce the bandwidth to ~<0.5 Angstrom (dependant upon used telescope). So you will have much more contrast and more details on the sun will be visible.
Technical data:

  • Aperture: 60 mm
  • No central obstruction
  • Bandwidth double stacked: <0,5 Angstrom
  • Tuning: tiltable Etalon
  • Housing diameter: 95 mm
  • Length: 85 mm
  • Weight: 0.85 kg
  • Front thread: M90x1 female thread
  • Rear thread: M90x1 male thread

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 <0.7 Angstrom.
