H-alpha LUNT LS100THa B1200 Solar Telescope H-alpha LUNT LS100THa B1200

The LS100THa is a complete H-alpha Solar telescope with a diameter of 102mm (unobstructed!) and a focal length of 714mm. An internal Etalon filter with fine tilt adjustment by air pressure controlled by the Pressure Tuner system allows to maintain throughout the observation a bandwidth
. The Pressure Tuner system allows a better adjustment of the Etalon filter than other more rudimentary systems . The "Pressure Tuner" system allows to adapt the Etalon filter to different altitudes and atmospheric pressures in order to always offer the best optical performance.

The blocking filter is the B1200. The zenith prism on which the blocking filter is located, is equipped for 1.25" eyepieces and with a T2 thread for camera attachment.

Focusing is achieved very accurately thanks to the quality of the Starlight Instruments Feather Touch 2" double-speed (and 10:1 reduction between macro and micro) Crayford focuser. This focuser is supplied as standard with the instrument.

Additionally, this rig could be purchased with the optional Double Stack Etalon LS100FHa accessory (mounts externally on the front end and measures 100mm) or with the new DSII Double Stack internal system to be able to have a bandwidth of
