The new DSII eliminates the need for an external front mounted filter for double stackingDouble stacking provides a truly enhanced, high definition view of the Sun’s surface details.  It lowers the bandpass of the system from <0.7 Angstroms to <0.5 Angstroms, which produces startlingly sharp images.
In this system both Etalons are internally installed in the telescope. Both Etalons are equipped with Lunts' True Doppler Pressure Tuning system eliminating optical obstructions. The system then is 100% un-obstructed.  The DSII module can be easily "field" installed on all LS80THa telescopes. 

  • This Lunt 80mm Internal Double Stack Module is strictly for use with a Lunt LS80THa H-alpha Telescope.
  • Uses a Lunt Solar System Pressure Tuner for True Doppler Tuning.
  • The Lunt 80mm Internal Double Stack Module lowers Bandpass to <0.5 Angstroms.


Lunt Solar Systems currently offers 4 blocking filter apertures for use with our Etalon systems. The Blocking Filter houses additional filters which are required for the safety and performance of the solar package.  Lunt Solar blocking filters contain a unique filter system. Lunt will only warranty safety or performance when a Lunt blocking filter is paired with a Lunt H-alpha filter or telescope.
