Lunt Solar Systems - Solar Telescopes

This refractor based system has a precision aligned air spaced doublet with
a 60mm aperture. The focal length is 600mm providing a ~5.4mm image thru a
6mm blocking filter. Course focus adjustment via a slide tube. Fine
adjustment is achieved with a Crayford style focuser with 10:1 reduction
standard.

The scope has an internally mounted tunable etalon system which has been
double passed using our Patent Pending technology.
The optical system has been optimized for the Hydrogen-alpha wavelength.
