You can now enjoy observing the ever changing
phenomenon of the sun in hydrogen alpha at the most reasonable price. For
over eighteen 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. The 1.5 band-width also yields some
surface detail including flares. Each system comes complete and ready to
attach to telescope. The system includes a red pre-filter and H-alpha filter
mounted in a tilting (fine-tuning) mechanism. (Type 2 and 3 series filters
will not work as a pre-filter since the 656.3 band-width is not
transmitted). H-Alpha filters generally do not work with newtonians as there
is not enough focus travel. Piggy-backing a small refractor is recommended
since a large aperture is not necessary for solar observation.
Enhance your deep sky viewing with the latest in
multi-layer coating technology. Over three years in development. Our filters
transmit desired wave-lengths in a very steep slope vs gentle transition
slopes in competitive brands. This means better contrast & overall
Available for 1.25" and 2" eyepieces.

When ordering a solar or H-Alpha filter, please
specify telescope brand, focal length and outside diameter measurement of
telescope tube. The cost of any filter is based on the actual aperture of
your instrument. The cell that the filter is mounted in will be sized to fit
over the end of the tube.
We manufacture filters to fit all brands and
apertures of optical instruments including telescopes, binoculars, cameras,
telephoto lenses and video cameras.
Thousands of our filters are in use world wide.
All of our Solar filters and Nebular filters are
manufactured in the U.S.A.
