Lunt Solar Systems - LS60THa - 60mm H-Alpha Telescope

Lunt Solar Systems -  60mm H-Alpha Telescope - LS60THa
 

• The Lunt Solar Systems LS60THa Hydrogen-Alpha Telescope comes with a precision aligned 60mm singlet lens and an internal etalon system with tune adjustment that allows a maximum of <0.75 Angstrom bandpass.
  
  
• Reveals excellent details on both the solar surface, limb edge, flares and prominences.
  
  
• This Lunt 60mm Hydrogen-Alpha Telescope has a focal length of 500mm.
  
  
• 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 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 straylight 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 6mm blocking filter (sold separately). 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.

You can achieve coarse focus adjustment with a slide tube, and then fine adjustments to focus are accomplished via the included dual-speed 2" Crayford style focuser with 10:1 reduction. Its clam shell mount is compatible with most tripods and mounting holes are all part of the Lunt Solar Telescope System.... Right down to the stylized white pearl paint with anodized black trim and included foam lined hard case.
