product description


DSII module for all Lunt Solar Systems telescopes with 80 mm and 100 mm aperture. Internal double stack filter with air-pressure tuning system. Reduces the bandwidth to <0.5 Angstrom!


The new DSII system from Lunt Solar Systems reduces the bandwidth of all LS80/LS100THa 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 the tuning system “Pressure Tuner”! This "Pressure Tuner" system allows a better Etalon adjustment than other systems.
The DSII module will be easily installed at all LS80/LS100THa telescopes, it is not needed to return the telescope to the manufacturer.

The DSII module is designed for use at the LS80THa telescope only. Because all necessary filters for safety (ERF...) are installed in the LS80THa/LS100THa, the DSII module has no extra filter like this. Therefore the module cannot be used without LS80THa/LS100THa telescope!

Due to the renunciation of other, unnecessary filter the sun's image is brighter than at other double-stack systems. Therefore prominences can be observed clearly and in detail that would be very strong dimmed at other double-stack systems.
