Lunt Solar Systems - Calcium-K Module with Feather Touch focuser and B1800 Blocking Filter for LS200THaDS

The LS200THaDS is a complete Solar Telescope. The Newtonian based system is a telescope with rings and has a aperture of 200 mm.
The focal ratio is F/6 with a collimation set . The focal length is 1200mm providing a ~11.8 mm image through a 18 mm blocking
filter as a standard , optimized for visual observing and webcam imaging. For 35 mm Camera imaging we recommend to order the
Telescope with the B3200 Blocking filter for better illumination due larger necessary backfocus. 

This is an optional Calcium-K module for the LS200THaDS telescope. Internal narrowband filters allow a <2,4 Angstrom bandpass.

It includes a second focus system 90 degrees from the Ha. This system will house CaK filter optics. This allows viewing of the
Sun in Ha or CaK at the same telescope.

To this version belongs a B1800 Blocking Filter and a Starlight Instruments Feather Touch focuser with 10:1 reduction. We offer
you a second version with a normal Crayford focuser, too.
