Home Telescopes Lunt Solar Telescopes Lunt 60mm H-alpha OTA B600 BF & Crayford Focuser Solar Telescope
The LS60THa is a complete Solar Telescope with 60mm aperture and 500mm focal length. An internal etalon with tune adjustment allows for a <0.75 Angstrom bandwidth. 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. Blocking filter is the B600. 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 adjustment is achieved with a Crayford style focuser with 10:1 reduction.
