Sluneční dalekohled LUNT LS100THa/B3400 H-alpha
Refraktor. Apertura: 102 mm. Ohnisková vzdálenost: 714 mm
Complete H-alpha solar telescope with 102mm aperture, <0.7 Angstrom bandwidth, advanced air-pressure tuning system, B3400 blocking-filter, and Feather Touch focuser.
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 an 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 an 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.
