The LS60/Ha is a complete Solar Telescope. The refractor based system has a precision aligned singlet chromatic lens with a 60mm aperture. The front singlet lens reduce half the stray light of an achromat, fully eliminate the possibility for on axis coma, astigmatism, decentering aberrations and provides with the matched collimation lens set a full spherical corrected flat-field Solar-Telescope. The focal length is 500mm providing a ~4.5 mm image through a 6mm blocking filter. Fine adjustment is achieved with a Crayford style focuser or feather touch focuser with 10:1 reduction standard. An internal etalon with tune adjustment allows for a <0.8 Angstrom bandpass.
