Designed for Coronado's SolarMax II 90mm telescope, the SolarMax II 90mm Double Stacking Etalon Filter from Coronado increases visibility of surface detail and active regions on the Solar disc. The filter reduces the normal bandwidth of a SolarMax telescope or a filter set from .7A performance to a more restrictive .5A and features a RichView tuning system for direct tuning of the primary etalon. This filter cannot be used as a standalone solar filter because of possible severe eye damage.
Carry and protect your equipment with a case or cover.
