Lunt 60mm Calcium Solar-Telescope with B1200 blocking filter and 2" Crayford Focuser The LS60/CaK is a complete Solar Telescope for the Calcium-K line. The refractor based system has a precision aligned CaK optimized doublet achromat with a 60mm aperture. The focal length is 500mm providing a ~4.5mm image thru the B1200 blocking filter. Fine focus adjustment is achieved with a Crayford focuser with 10:1 reduction.
Internal narrowband filters allow for a <2.4 Angstrom bandpass. Primarily an imaging system due to the difficulty of many to visually see everything that CaK has to offer. Lunt Solar will be introducing an imaging package for use with this system.
