The Lunt 60mm Ha OTA + DS-50 + B1200 BF + Feather T + P Tuner is a complete H-alpha Solar Telescope with 60mm aperture and a additional 50mm Double-Stacked Etalon system. The telescope can be used with <0.7 Angstrom bandwidth or with <0.5 Angstrom bandwidth. With B1200 Blocking Filter for smaller vignetting at imaging, superb quality Starlight Instruments Feather Touch focuser, and new air-pressure tuning system!

This telescope will be delivered with two matched Etalons, a internal one and a external. The internal etalon with new air-pressure tuning system adjustment allows for a <0.7 Angstrom bandwidth. This "Pressure Tuner" system allows a better Etalon adjustment than other systems. The “Pressure Tuner” system adapted the Etalon to varying altitudes and atmospheric pressures for always optimal performance. 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.

The best views of the Sun are undoubtedly seen thru a dual etalon system. The reduction in bandpass from an estimated 0.7 Angstrom to 0.5 Angstrom just seem to bring the Sun's surface to life. 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 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.

The focal length of the telescope is 500mm. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection. The B1200 Blocking Filter provides a smaller vignetting for imaging. Fine focus adjustment is achieved with a Starlight Instruments 2" Feather Touch focuser with 10:1 reduction.

Supplied with an Aluminum finished hard case with fitted foam.
