Description

Caution: This filter cannot be used as a stand alone solar filter. Immediate and irreversible eye damage may result.

Coronado by Meade SolarMax II 90mm Double Stacking Etalon with RichView tuning system. 90mm diameter primary H-Alpha etalon filter. This add-on filter reduces the normal bandwidth of a SolarMax 90 telescope or filter set from the single stack 0.7A performance to a more restrictive 0.5A, increasing visibility of surface detail and active regions on the Solar disc. Must be combined with a primary SolarMax 90 filter and blocking filter or complete Coronado SolarMax 90 telescope.
