Internal Double Stack Module for 80mm Telescope

(1 customer review)


  • Add an internal double-stacking module to a Lunt LS80THa solar telescope for a lowered bandpass of <0.5 Angstroms!
  • The LS80THa DSII includes a pressure tuner for true Doppler tuning.
  • Add the DSII to a new LS80THa at the time of order, or add it to an LS80THa you already own, no trip back to the factory required!

LS80THa/PT/DSII – Internal Double Stack Module for LS80THa

Double stacking provides a truly enhanced, high definition view of the Sun’s surface details. Notably, it lowers the bandpass of the system from <0.7 Angstrom to <0.5 Angstrom, which really makes the surface “pop”!

The Lunt LS80THa can be internally double-stacked at the time of purchase or anytime thereafter.  Furthermore, the LS80THa does not need to be returned to the factory for double-stacking.

You can purchase the LS80Tha single stack solar telescope initially and add the DSII to make it a double stack unit later.  This will make it more affordable to purchase our most popular solar telescope and still have room for upgrades.  Once you upgrade your Lunt LS80THa with the DSII, you will be able to see the finer details not previously visible.

The image shows a DSII Internal Double-Stacking Module installed on a LS80THa.  All equipment, other than the DSII module itself, is sold separately.

    The double-stack greatly improves view and is easy to tune. Thanks.
