The Lunt LS80THa/DSII double-stack module for LS80THa from Lunt Solar Systems reduces the bandwidth of all LS80THa telescopes to <0.5 Angstrom. The DSII eliminates the need for an external front mounted filter for double stacking. In this system both Etalons are internal installed in the telescope, and both Etalons are equipped with a Pressure Tuner. The "Pressure Tuner" system allows a better Etalon adjustment than other systems.The DSII module is easily installed in all LS80THa telescopes and it is not necessary to return the telescope to the manufacturer.The LS80THa/DSII double-stack module is designed for use with the Lunt LS80THa telescope only, as all Energy Rejection Filters (ERF) necessary for safety are installed in the LS80THa. The DSII module has no additional ERF filters and so this module cannot be used without LS80THa telescope!As the Lunt LS80THa/DSII double-stack module does not contain unnecessary ERF, the sun's image is brighter than those in alternative designed double-stack systems and so prominences can be observed clearly and in greater detail than would visible in a very strongly dimmed double-stack system.
