Details

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 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 tilt 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.  

*BLOCKING FILTERS ARE REQUIRED ON ALL LUNT SOLAR SYSTEMS

Lunt Solar Systems currently offers 4 blocking filter apertures for use with our 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.

Focal Length Specifications (Visual Use):

• B600 :  For visual use on telescopes with focal lengths up to 600mm
• B1200: For visual use on telescopes with focal lengths up to 1200mm
• B1800: For visual use on telescopes with focal lengths up to 1800mm
• B3400: For visual use on telescopes with focal lengths up to 3400mm (only available in straight-thru design)

Focal Length Specifications (Imaging Use):

 When imaging with a Lunt Solar System it is recommended that the user opt for the next larger Blocking Filter than that recommended for Visual use.  This is due to the fact that most Imaging Systems require additional “backfocus”.  This requires that the Blocking Filter be moved further up the light cone. As a result the aperture of the Blocking filter needs to be larger to allow for the larger cone size.

• B600:   For imaging use on telescopes with focal lengths up to 400mm
• B1200: For imaging use on telescopes with focal lengths up to 600mm
• B1800: For imaging use on telescopes with focal lengths up to 1200mm
• B3400: For imaging use on telescopes with focal lengths up to 1800mm (only available in straight-thru design)

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.
