Double Stack Filter for Lunt 130 mm & 152 mm Telescopes


  • Add an internal double-stacking module to a Lunt 130 mm or Lunt 152mmtelescope for a lowered bandpass of <0.5 Angstroms!
  • The LFPT includes a pressure tuner for true Doppler tuning.
  • Add it yourself to your own Lunt 130 mm or Lunt 152m mm Telescope, no trip back to the factory required!




LFPT Internal Double Stack Module for Lunt 130 mm & 152 mm Telescopes

Double stacking provides a truly enhanced, high definition view of the Sun’s surface details. It lowers the bandpass of the system from <0.65 Angstroms to <0.45 Angstroms. This will significantly make the surface features on the Sun “pop”! The Lunt 130 mm and 152 mm  can be internally double-stacked at the time of purchase or anytime thereafter and does not need to be returned to the factory for double-stacking.

Subsequently, add the DSII internal double stack module to make it a double stack unit later.  This will make it more affordable to purchase our best solar telescope and still have room for upgrades.  Once you upgrade your Lunt LS130MT with the LFPT internal double stack module, you will be able to see the finer details on the Sun that were not previously visible.
