Double-stack filter for the LS40THa solar telescopes

With the so-called ?double-stacking?, the FWHM of H-alpha systems is reduced. With a narrower FWHM, the contrast on the solar surface is drastically increased, making significantly more details visible.

Double-stacking is also possible with the LS40THa telescopes with a reduction of the FWHM to just <0.55 Angstroms. Lunt Solar Systems has specially designed this LS40FHa double-stack filter in a compact housing for this purpose. The filter can be screwed directly onto the LS40THa telescopes.

Aperture:	40mm
FWHM:	<0.55 Angstroms
Tuning:	mechanical tilt tuning

*[can only be used together with an LS40THa telescope]**:
