Thousand Oaks Optical - H-Alpha Solar Prominence Filter Sets

For over twenty 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.
