Complete H-alpha solar telescope with 60mm aperture and additional 50mm double-stack filter system. The telescope can be used with <0.7 Angstrom bandwidth or with <0.5 Angstrom bandwidth.

This telescope will be delivered with two matched Etalons, a internal Etalon and a external. The LS60THaDS50 could be used only with the internal H-alpha filter at <0.7 Angstrom and a aperture of 60mm, or together with the front mounted external H-alpha filter at <0.5 Angstrom bandwidth and 50mm aperture.

By reducing the bandwidth from estimated 0.7 Angstrom to 0.5 Angstrom more details on the solar surface will become visible. 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 (matched) and both need to be adjustable (Tuning) such that all ghosts images could be 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.

The internal Etalon of the telescope is equipped with the advanced air-pressure tuning system ?Pressure-Tuner?. The Etalon of the external double-stack filter is provided with mechanical tilt-tuning system.

Blocking-filter is the B1200. The B1200 is good for visual solar observing, and also good for solar imaging.
The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25” eyepieces and with a T2 camera connection.

Fine adjustment is achieved with a Crayford style focuser with 10:1 reduction.
