LuntSolarSystems - Solar Telescope LS100THa 100mm H-alpha with B3400 blocking filter, Feather Touch Focuser and Pressure Tuner
The LS100T/Ha is a complete Solar Telescope. The refractor based system has a precision aligned singlet chromatic lens with a 100 mm aperture. The front singlet lens reduces the stray-light over an achromat by half. With the matched collimation lens set, it also fully corrects on axis coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field Solar-Telescope. The focal length is 800 mm providing a ~7.3 mm image thru a 34 mm blocking filter. Course focus adjustment is via a slide tube. Focusing is achieved with a High Precision 2" Starlight Feather Touch Friction focuser with the a 10:1 reduction as standard equipment.
An internal etalon with tune adjustment allows for a <0.7 Angstrom bandpass.
Addionally the system may also be purchased with the 100mm external, front mounted Double Stack Etalon LS100FHa for a bandpass of <0.5 Angstrom.
