Product Description

LS40FHa Double Stack Solar Filter

The Lunt LS40FHa Solar Filter is a 40 mm aperture (no central obstruction) integrally tuned etalon for use on Lunt Dedicated 40 mm Telescopes

The Lunt LS40FHa Double Stack Unit is intended for use with the Lunt 40mm Dedicated Hydrogen Alpha System and requires a Lunt Solar Systems Blocking Filter (this is a safety requirement).

Because the LS40FHa Solar Filter has an estimated bandpass of <0.70 Angstrom it is capable of providing high contrast views of both surface and edge detail. Significantly, adding an additional etalon system (double-stacking) will reduce the bandpass to ~<0.50. Allowing for higher resolution viewing and/or imaging.
