The LS60THa is a telescope for observing the sun in H-alpha, with 60mm aperture (no central obstruction) and 500mm 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 with a Crayford style focuser with 10:1 reduction.
