The new DSII System reduces the bandwidth of the LS152THa telescopes to <0,5 Ångström!
By this, the contrast is enhanced significantly.

With the DSII, no front-filter is necessary for double-stacking anymore. Here, both etalons are installed internally in the telescope, and both are equipped with the "Pressure Tuner". With this, the etalons can be adjusted far more precise than with conventional systems.

The Lunt LS152THa can be internally double-stacked at the time of purchase or anytime thereafter. The LS80THa does not need to be returned to the factory for double-stacking.

As the DSII Module was designed for being used exclusively in the LS152THa telescope, and all necessary energy rejection filters are already installed in this telescope, this module contains no additional energy rejection filters.

For this reason, the module cannot be used without the LS152THa telescope!

By not using additional, unnecessary filters, the image of the sun remains brighter than with other double-stack systems, so high magnifications are possible without the image getting too dark.
