Lunt 60mm Tilt Tuned Solar Telescope with B1200 Filter and 2" Crayford Focuser
The Lunt LS60THa tilt-tuned solar telescope is a complete h-alpha solar telescope. The refractor-based system has a precision-aligned singlet chromatic lens with a 60 mm aperture. The front singlet lens reduces half the stray light of an achromat, fully eliminating the possibility of on-axis coma, astigmatism, de-centering aberrations, and provides, with the matched collimation lens set, a full spherical corrected flat-field solar telescope.
The focal length is 500 mm, providing a ~4.5 mm image through a 6 mm blocking filter. Fine adjustment is achieved with a 2″ Crayford-style focuser or Feather Touch focuser with 10:1 reduction. An internal etalon with tilt-tune adjustment allows for a <0.8 Angstrom bandpass.

B600 – for visual use
