Product Details
The LS60THa is a complete Solar Telescope. The refractor based system has a precision aligned singlet chromatical lens with a 60mm 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 500mm providing a ~4.5 mm image through a 6mm blocking filter. Fine adjustment is achieved with a Crayford style focuser with 10:1 reduction standard. An internal etalon with tune adjustment allows for a <0.8 Angstrom bandpass.
