The LS60THa is a versatile H-alpha solar telescope with 60mm aperture and 500mm focal length. Its internal Etalon with tuning adjustment allows for a <0.75 Angstrom bandwidth. With the Lunt matched eyepieces, the LS60THa is fully corrected for on axis coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field solar telescope.
This scope's 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. The blocking filter is wide enough for imaging use, but dedicated solar imagers should look at the B1200 version of this telescope for a wider field of view.
Fine adjustment is achieved with the exquisite Starlight Instruments 2" Feather Touch focuser with 1.5" travel and 10:1 reduction for ultra-precise control and superb engineering.
