The Coronado SolarMax II 90mm Etalon/ RichView Tuner consists of a H-Alpha 90mm narrowband unit for use in doublestacking along with a matching RichView Tuner. Cannot be used without secondary interference filter.
Coronado SolarMax II 90mm H-Alpha Etalon/ RichView Tuner Package
By applying the Coronado SolarMax II 90mm Etalon/ RichView Tuner to your current SolarMax 90 system, you can achieve a <0.5 Ångstrom passband, centered on the 6562.8 Ångstrom H-Alpha line and the sub-Ångstrom passband width which gives a perfect balance of prominence and surface features. The assembly is thermally stable at 0.005Å per degree Centigrade, so there is no drifting off the H-Alpha line as the filter heats up during normal observing.

- Questions & Answers
Product QuestionsI already have a solarmax II 90 mm external etalon threaded directly to my TV-102 iis with a BF-30 blocking filter at the focuser end. I would like to order this second etalon for double stacking.
Can you please confirm that I will need to use the Coronado filter adapter AP190 between my existing etalon and the second external etalon and if so, how do I order this adapter if I don't find it listed here on your website?
