Lunt Internal Double Stack Module for LS100THa - DSII/LS100THa

When you Double stack your solar telescope, you experience a truly enhanced, high definition view of the Sun’s surface details.

Most importantly, it lowers the bandpass of the system from <0.7 Angstroms to <0.5 Angstroms.

Significantly, this will really makes the surface detail of the Sun “pop”!

The Lunt LS100THa can be internally double-stacked at the time of purchase or anytime thereafter.

As an advantage to you, the LS100THa does not need to be returned to the factory for double-stacking as long as you have the red anodized front cell on your telescope.

If you have an older model (just a white tube with no red) you will need to upgrade the scope before using the internal double stack DSII-LS100THa.

Should that be your situation, contact us for upgrade information.

  • Add an internal double-stacking module to a Lunt LS100THa solar telescope for a lowered bandpass of <0.5 Angstroms!
  • The LS100THa DSII includes a pressure tuner for true Doppler tuning.
  • Add the DSII to a new LS100THa at the time of order, or add it yourself to your own LS100THa, no trip back to the factory required!
