The LS60THaDS is a complete Solar Telescope.

This refractor based system has a precision aligned singlet chromatical lens with a single pass 60mm and a double stacked 50mm unobstructed aperture. The focal length is 500mm providing a ~4.5mm image.
Course focus adjustment via a slide tube. Fine adjustment is achieved with a Starlight Instruments 2" Feather Touch focuser with 10:1 reduction standard.

The scope has an externally and internally mounted factory matched tunable etalon system for use at both <0.8 Angtroms and <0.55 Angstroms. The optical system has been optimized for the Hydrogen-alpha wavelength.

The Double Stack System...
The best views of the Sun are undoubtedly seen thru a dual etalon system. The reduction in bandpass from an estimated 0.8 Angstroms to 0.5 Angstroms just seem to bring the Sun's surface to life. Larger apertures on a good seeing day usually result in a WOW! from those who are lucky enough. Adding a second etalon to an existing etalon is not quite as simple as it may seem. Both etalons need to be brought on line (tuned) and both need to be tiltable such that all ghosts are eliminated. Ideally the transmission curves should overlap perfectly when on band to provide for the best possible resolution and contrast.
Both etalons in this system will be matched at the factory in order to provide a system that is both optimized for performance and the elimination of ghosting.

• An infra red reflecting window (ERF) is provided early in the optical path to remove unwanted heat from the system.
• An optically optimized collimating system ensures true collimation, coma correction, and off axis (sweet spot) reduction.
• Our newly designed Induced Transmission Filter (see "safety") will ensure long term safety and performance.

The Blockingfilter B600 with 6 mm aperture is the least expensive entrance providing a good illuminated visuel view and large enough FOV for CamCorder imaging.
