More Info

Required to double-stack a second external primary Etalon filter. Telescope and double stacking filter sold separately.

When double-stacking etalon filters, the original 0.7 angstrom bandpass of the Hydrogen-Alpha telescope is reduced to .5 angstrom, dramatically increasing visibility of surface detail such as granularity and active regions on the surface of the Sun.

CAUTION: Never look at the Sun, either directly or through a telescope, without a professionally made protective solar filter installed that completely covers the front of the instrument, or permanent eye damage could result.

Designed and Manufactured in North America.
