LUNT • 60mm H-alpha SolarTelescope, B600 Blocking Filter and 2" Crayford Focuser • LS60THa/B600/C
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 by 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 spherically corrected flat-field SolarTelescope. The focal length is 500mm providing a ~4.5 mm image thru a B600 (6mm) Blocking Filter. Fine adjustment is achieved with a dual speed Crayford style focuser with 10:1 reduction standard. An internal Etalon, optimized at the Hydrogen-alpha wavelength of 656.28nm, with tune adjustment of +0.0/-0.4 Angstroms, provides a <0.75 Angstrom bandpass.
You can achieve coarse focus adjustment with a slide tube, and then obtain 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 foam lined hard case are all part of this amazing Lunt Solar Telescope System.
* BLOCKING FILTERS ARE REQUIRED ON ALL LUNT SOLAR SYSTEMS *
Lunt Solar Systems currently offers 4 blocking filter apertures for use with their Etalon systems. The Blocking Filter houses additional filters which are required for the safety and performance of the solar package. Lunt Solar blocking filters contain a unique filter system. Lunt will only warranty safety or performance when a Lunt blocking filter is paired with a Lunt H-alpha filter or telescope.
Required Blocking Filters:
B600 for standard visual use (Included)
B1200 for larger field of view and imaging applications (Optional Upgrade)
B1800 optimized large field for viewing or imaging (Optional Upgrade)
