The LS200THaDS is a complete Solar Telescope. The Newtonian based system is a telescope with rings and has a
aperture of 200 mm. The focal ratio is F/6 with a collimation set . The focal length is 1200mm providing a
~11.8 mm image through a 18 mm blocking filter as a standard , optimized for visual observing and webcam
imaging. For 35 mm Camera imaging we recommend to order the Telescope with the B3200 Blocking filter for
better illumination due larger necessary backfocus.
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.
The LS60THaDS50 is a complete Solar Telescope. The scope has an externally and internally mounted factory
matched tunable etalon system for use at both <0.8 Angtroms and <0.55 Angstroms. The optical system has been
optimized for the Hydrogen-alpha wavelength.
