The LS100THa is a telescope for observing the sun in H-alpha, a precision aligned ED refractor with 102mm aperture (no central obstruction) and 714mm focal length. An internal Etalon with advanced air-pressure tuning system “Pressure-Tuner” provides <0.7 Angstrom bandwidth. This “Pressure Tuner” system allows a more accurate Etalon adjustment than other systems. The “Pressure-Tuner” system adapted the Etalon to varying altitudes and atmospheric pressures for always optimal performance. The Etalon is installed safely inside the telescope-tube.
Fine adjustment is achieved by a 2" Starlight-Instruments Feather-Touch focuser with 1.5" travel and 10:1 reduction.
