Coronado SolarMax II Double Stacking Units

These external etalon filter elements are to be used with complete SolarMax telescopes; they may not be used as a stand alone filter with other telescopes. Adding one of these double stacking modules to the corresponding SolarMax II telescope reduces the system bandpass to <0.5 angstroms, revealing far greater surface detail on the sun. Each filter includes Coronado's new RichView tuning. These filters thread directly onto the front of the corresponding SolarMax II telescopes. Additional adapter rings are necessary to mate these filters with the original SolarMax telescopes produced before 2011.
