LUNT LS100THa OTA (no blocking filter!)

H-alpha Solar Telescope with 102mm aperture and <0.7 Angstrom bandwidth, with advanced air-pressure tuning system, and Feather-Touch focuser. Will be delivered without blocking-filter, can only be used with additional blocking-filter!

This telescope will be delivered without blocking-filter. We offer many additional available blocking-filters in various sizes, in 90° star-diagonal, or straight extension-tube. You can use these blocking-filters at this telescope.
PLEASE NOTE: You can not use this telescope without additional blocking-filter!

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.
