Lunt LS60THa/FTPT OTA (no blocking Filter!)

Lunt LS60THa/FTPT OTA (no blocking filter!)

H-alpha Solar Telescope with 60mm 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 all these blocking-filters at this telescope.
PLEASE NOTE: You can not use this telescope without additional blocking-filter!

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 by a Starlight-Instruments 2" Feather-Touch focuser with 1.5" travel and 10:1 reduction.
