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 B1800 blocking filter. Course focus adjustment via a slide tube. Focusing is achieved with a High Precision 2" Starlight Feather Touch focuser with 10:1 reduction standard.
An internal etalon with tuneable adjustment allows for a <0.8 Angstrom bandpass.
The Internal module has an optimized collimating system to reduce off axis abberation.
The system may also be purchased with a 100mm External Filter for a bandpass of <0.5. Call for details....
