About the Lunt 60mm DoubleStack H-Alpha Telescope - B1200, Pressure Tuner & 2" FeatherTouch Focuser...

The Lunt 60mm DoubleStack H-Alpha Telescope will be delivered with two matched Lunt Solar Telescope Etalons, a internal one and a external. The internal etalon with new air-pressure tuning system adjustment allows for a Lunt Solar Telescope LS60THaDS50 could be used only with the internal H-alpha filter at


The best views of the Sun are undoubtedly seen through a dual etalon system like the Lunt 60mm DoubleStack H-Alpha Telescope. The reduction in bandwidth 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 Lunt Solar 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 Lunt Solar Telescope 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 Lunt 60mm DoubleStack H-Alpha Telescope is 500mm, Blocking Filter is the B1200. The star diagonal in which the Lunt Solar Blocking Filter is installed, is equipped as standard for 1.25" Lunt Solar Eyepieces and with a T2 camera connection. Fine adjustment is achieved with a 2" FeatherTouch focuser with 10:1 reduction standard.


Don''t forget... We also carry many fine Lunt Solar Telescope Accessories, such as Lunt H-Alpha Solar Filters, Lunt Calcium K Solar Filters, Lunt Solar Eyepieces, and even a Lunt Solar Imager!
