Lunt Solar Systems - 100mm H-Alpha B3400 Feathertouch  Telescope

• The Lunt Solar Systems LS100THa Hydrogen-Alpha Telescope comes with a precision aligned 100mm singlet chromatical lens. 
  
  
• Internal etalon system with tune adjustment that allows a maximum of <0.75 Angstrom bandpass. Internal module will have an optimized collimating system to reduce off axis aberration.
  
  
• This Lunt 100mm Hydrogen-Alpha Telescope has a focal length of 800mm.
  
  
• The B3400 model includes a 2" dual speed 10:1 Feathertouch focuser, a clam shell mounting ring, and a foam-lined case.

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 34mm 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 giving excellent detail on all aspects of the solar image.
