H-alpha (.9 Angstrom) Filters

For 35 years we’ve manufactured the most popular white light filters in the world. With our white light filter, excellent views of sunspots and granulation are easily seen. In H-alpha light, spectacular prominence activity can be seen at the limb. Flares are also visible on the surface along with the same white light details visible with our standard filters. The two-part system is easy to use and can be setup in less than a minute.
