The LS100THa/B3400 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 B3400. The B3400 is good for solar imaging. We recommend a additional 90° star diagonal for visual observing. The straight extension tube in which the blocking filter is installed, is equipped as standard with a connection for 2” eyepieces and with a adapter for 1.25” eyepieces.
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.
