Lunt 100mm Ha Etalon Filter

Price is based on R7.00/$.

Double-Stack Etalon for all LS100FHa filters and LS100THa 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: 100 mm
  • Bandwidth double stacked: <0,5 Angstrom
  • Tuning: tiltable Etalon
  • Housing diameter: 162 mm
  • Length: 101 mm
  • Front thread: M120x1.5 female thread
  • Rear thread: M120x1.5 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.

A deposit of 70% is required.  Availability is typically 6 weeks depending on availability by supplier - please enquire.
