The Coronado SolarMax II Double Stacking Etalon with RichView tuning system connects to your SolarMax telescope or filter set to boost the contrast of surface features of the sun even further than a single stack filter by itself.

This add on filter reduces the normal bandwidth of a SolarMax 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 filter and blocking filter, complete Coronado SolarMax 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.

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.
