Internal Double Stack Module

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.

    Lunt doesn’t exaggerate. This model really does work as advertised. Yes the surface detail is enhanced but what I find the most interesting about this DS unit is the following. I can tune it and see both surface detail and prominences at the same ti!me. Can’t do that in SS mode cause you have to constantly tune to see one or the other. I just tune the SS first, then tune the DS and forget about it. Never take it off. Great value compared to the external stack module. Lunt rocks!
