The Double-Stack Etalon Solar-Filter for all LS100FHa Filter-Systems and LS100THa Telescopes.
Please note, THIS ITEM IS NOT A STAND-ALONE UPGRADE KIT FOR A REFRACTOR TELESCOPE! This is an addition to a solar telescope to increase its contrast and detail by reducing the bandwidth..

Includes:

  • LS100FHa Main Filter
  • Aluminium Transport case



Adding this additional Double-Stack etalon system will reduce the bandwidth to about <0.5 Angstrom (dependant upon used telescope).
So you will have much more contrast and more details on the Sun will be visible.

Technical Specification:
Aperture: 100 mm
Bandwidth double stacked: <0.5 Angstrom
Tuning: tiltable Etalon
Housing diameter: 162 mm
Length: 101mm
Front thread: M120x1.5 female thread
Rear thread: M120x1.5 male thread
Weight: TBC

Please note: it comes without a 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 an optional blocking filter, then the bandwidth is <0.7 Angstrom.

AVAILABLE ON BACK ORDER! (ETA: about 1-3 weeks)
