About this product

Coronado Personal Solar Telescope (PST) 40mm Double Stacking Etalon

Coronado SolarMax II 40mm Double Stacking Etalon with RichView tuning system. 40mm diameter primary H-Alpha etalon filter.

This add on filter reduces the normal bandwidth of a SolarMax 40 telescope or filter set from the single stack .7A performance to a more restrictive .5A, increasing visibility of surface detail and active regions on the Solar disc.

MUST be combined with a primary SolarMax 40 filter and blocking filter, complete Coronado SolarMax 40 telescope, or a PST 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.

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

NOTE: Coronado PST telescope shown in photo not included
