H-alpha Solar FiltersWith the H-alpha filters from Lunt Solar Systems you can upgrade normal astronomical telescopes for observing the sun during the daylight. The systems includes an Etalon filter for front mounting on the telescope and a blocking filter for the focuser. There is a large assortment of adapter plates for different telescopes available for the front mounting of the H-alpha filter. The blocking filters are installed in star diagonals, available alternatively for 1.25” or 2” focuser. These star diagonals are equipped with a reception for 1.25” eyepieces and a T2-connection for cameras on the eyepiece side. Which blocking filter size is the right one depends on the focal length of your telescope and the planned application. The B600 could be used visual at telescopes up to 540 mm focal length, the B1200 up to 1080 mm, the B1800 up to 1620 mm, and the B3400 up to 2880 mm focal length. If you want to image the sun, it will be better to use the next larger blocking filter.
LS60FHa FiltersThese H-alpha filters have full 60 mm clear aperture without obstruction, despite its size! The bandwidth is <0.7 Angstrom, with double-stacking you get <0.5 Angstrom. The filters are installed in the same housing as the smaller LS50FHa filters and can also be combined with the 60 mm LS60THa telescopes.

Note: Option without Blocking Filter! Only for use as double-stack filter, or together with a additional available blocking filter. If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is <0.75 Angstrom.
