Home Telescopes Lunt Solar Telescopes Lunt LS60THa/B600FT H-alpha Solar Telescope
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.Aperture: 60 mmFocal length: 500 mmBandwidth: internal Etalon with <0.75 AngstromTuning: tiltable EtalonBlocking Filter: B600 with 1.25" and T2 connectionFocuser: Starlight Instruments Feather Touch with 10:1 reductionWeight: 2.9 kgLength: 39 cm
