Description

ETA: September

Lunt LS40FHa Front Mount 40mm 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. 

  • It’s finally available! The Lunt Solar 40mm Double Stack Hydrogen-alpha Filter.
  • LS40FHa solar filter front-mounted non-obstructed hydrogen-alpha filter for use with the Lunt Solar Systems 40mm Dedicated Hydrogen Alpha Telescope
  • Attaches Directly to the Objective of the Lunt 40mm Dedicated Ha Telescope
  • Lowers the Bandpass of your existing LS40mm telescope to ~<0.5A !
  • DSII Requirements: Adapter is included with Double Stack Unit
