The LS60THa/B600 is a complete Solar Telescope. The refractor based system has a precision aligned air spaced doublet with a 60mm aperture. The focal length is 600mm providing a ~5.4mm image thru a 6mm blocking filter. Course focus adjustment via a slide tube. Fine adjustment is achieved with a Crayford style focuser with 10:1 reduction standard.

The LS60THa/B1200 is a complete Solar Telescope. The refractor based system has a precision aligned air spaced doublet with a 60mm aperture. The focal length is 1200mm. Course focus adjustment via a slide tube. Fine adjustment is achieved with a Crayford style focuser with 10:1 reduction standard.

Double Pass 60mm with Internal Etalon System (Patent Pending Design). The focal length is 600mm. An double pass internal etalon with tune adjustment allows for a <0.5 Angstrom bandpass.

Double Pass 60mm with Internal Etalon System (Patent Pending Design). The focal length is 1200mm. An double pass internal etalon with tune adjustment allows for a <0.5 Angstrom bandpass.

Single Pass 100mm Telescope with Internal Etalon System. The refractor based system has a precision aligned air spaced doublet with a 100mm aperture. The focal length is 800mm providing a ~7.3 mm image thru a 12 mm blocking filter. Course focus adjustment via a slide tube. Focusing is achieved with a High Precision Crayford style focuser  with the addition oft he 10:1 reduction standart.

The LS200THaDP is a complete Solar Telescope. The Newtonian based system is a telescope with rings and has an aperture of 200 mm. The focal ratio is F/6 with a collimating set. The focal length is 1200mm providing a ~11.8 mm image through a 18 mm blocking filter as a standart, optimized for visual observing and webcam imaging.
