Coronado Adapter Rings for Double Stack Filters
$24.99 - $34.99
Accepted Payment
  • Adapter for Coronado primary Ha filters
  • Allows two etalons to connect together for double-stacking
  • When coupled to 2nd etalon, reduces original 0.7 angstrom bandpass of the Hydrogen-Alpha telescope to 0.5 angstrom

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.
