The Double-Stack Etalon Solar-Filter for all LS60FHa Filter-Systems and LS60THa 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:

 

  • LS60FHa 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: 60 mm
No central obstruction
Bandwidth double stacked: <0.5 Angstrom
Tuning: tiltable Etalon
Housing diameter: 95 mm
Length: 85mm
Front thread: M90x1 female thread
Rear thread: M90x1 male thread
Weight: 0.85 kg

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)

LUNT LS60FHa (0550250)

Additional info about LS60FHa

These H-alpha filters have full 60 mm clear aperture without obstruction, despite its size! The bandwidth is <0.7 Angstrom, with double-stacking you get about <0.5 Angstrom.
The filters are installed in the same housing as the smaller LS50FHa filters and can also be combined with the 60 mm LS60THa telescopes.
