| LS60THa | |
 |
|
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 reduce half the straylight of an achromat , fully eleminate 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 thru 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 LS100T/Ha is a complete Solar Telescope. The refractor based system has a precision aligned singlet chromatical lens with a 100mm aperture. The front singlet lens reduce half the straylight of an achromat , fully eleminate 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 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 2" Starlight Feather Touch Frictionfocuser with the addition oft the 10:1 reduction standard.
An internal etalon with tune adjustment allows for a <0.75 Angstrom bandpass.
