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.

Includes patented RichView tuning assembly allows direct tuning of the primary filter etalon. No other commercially available Ha telescope can provide the tuning range and accuracy of the SolarMax II. Now you can tune for the highest contrast views of active regions, filaments and surface detail, or quickly and easily re-tune for prominences on the solar limb.
