The LS100THa/B1200 is a complete 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. Blocking-filter is the B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS100THa with B1800 or B3400 blocking-filter by using cameras with middle or large sized CCD chips. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25' eyepieces and with a T2 camera connection. Double-stacking is also possible at the LS100THa telescopes. It will reduce the bandwidth to < 0.5 Angstrom, much more details on the solar surface will become visible. There are two different possibilities for double-stacking at the LS100THa telescopes. The professional, but also expensive solution is the additional available LS100FHa front-mounted double-stack filter. A well priced possibility is the also optional available internal double-stack module LS100THa/DSII. Features:
