Lunt - 100mm Ha Telescope w/ Internal Etalon and B3400

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 through 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.

Additionally the system may also be purchased with the 100mm external, front mounted Double Stack Etalon LS100FHa for a bandpass
of <0.5 Angstrom.
