The New LS35THa The LS35THa dedicated Hydrogen-alpha telescope is the most compact 35mm etalon system currently available. An unobstructed, front mounted, 35mm etalon provides a bandpass of <0.75 Angstroms. Prominences and some surface detail can quickly be viewed through this very portable single stack system.

The LS60THa/B600 is a complete Solar Telescope. The refractor based system has a precision aligned air spaced doublet with a 60mm aperture. The focal length is 500mm 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.
