Details

The LS60THa is a complete Solar Telescope with 60mm aperture and 500mm focal length. An internal etalon with new air-pressure tuning adjustment allows for a <0.7 Angstrom bandwidth. This "Pressure Tuner" system allows a better Etalon adjustment than other systems. The “Pressure Tuner” system adapted the Etalon to varying altitudes and atmospheric pressures for always optimal performance.

With the matched collimation lens set, the LS60THa is fully corrected for on axis coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field Solar-Telescope. The blocking filter is the B1200, that provides a smaller vignetting for imaging. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection. Fine focus adjustment is achieved with an ultra-smooth Crayford style focuser with 10:1 reduction.
