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.
