Lunt LS60THa B1200 FT H-alpha Solar Telescope
The Lunt LS60THa/B1200FT H-alpha solar telescope is a complete H-Alpha Solar Telescope with 60mm aperture and 500mm focal length. An internal etalon with tuning adjustment allows for a <0.75 Angstrom bandwidth.
With the matched Lunt eyepiece set, the LS60THa is fully corrected for on axis coma, astigmatism and de-centring aberrations and provides a full spherically corrected flat-field Solar-Telescope.
The blocking filter in this particular instrument is the B1200, a generously wide filter that minimises vignetting for imaging. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and also features a T2 camera connection.
Fine adjustment is achieved with a Starlight Instruments 2" Feather Touch focuser with 1.5" travel and 10:1 reduction - these focusers are rightly regarded as the top in their field and provide the user with durability and extremely fine control.
