- This model includes a 2" dual speed 10:1 Crayford-style focuser, a clam shell mounting ring, and a foam-lined case.
The LS60/Ha (hydrogen alpha) Solar Telescope is a refractor based system which features a precision aligned singlet chromatical lens with a 60mm aperture. The front singlet lens reduces half the stray light of an achromat , fully eleminates the possibility for on-axis coma, astigmatism, or 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 thru a blocking filter (sold separately)*. Fine adjustment is achieved with a dual speed Crayford style focuser with 10:1 reduction standard. An internal Etalon, optimized at 656.28nm, with tune adjustment +0.0/-0.4 Angstroms, allows for a <0.75 Angstrom bandpass.
You can achieve coarse focus adjustment with a slide tube, and then fine focus adjustment via the included dual-speed 2" Crayford style focuser with 10:1 reduction. Its clam shell mounting ring (compatible with most tripods), stylized white pearl paint, anodized black trim, and included foam lined hard case are all part of the amazing Lunt Solar Telescope System.
