Coronado SolarMax II 40/ RichView Tuner Package for Double-Stacking SM40 Filter Set or Telescope, SME-40
This Coronado filter SME-40 SolarMax II 40/ RichView Tuner H-Alpha 40mm narrowband unit is for use in doublestacking. It cannot be used without secondary interference filter which means that you must use this filter with either a Coronado etalon/ blocking filter or Coronado H-alpha telescope. It comes with RichView tuner, and requires an adapter, which is sold separately.
Increase the amount of detail you can see through your SolarMax II 40 filter set or SolarMax telescope when you add a second filter!
This is a genuine SolarMax II 40 / RichView unit that will, when properly matched, narrow your bandpass to <0.5 angstroms, greatly increasing the amount of surface detail you can see and image with your SolarMax 40 telescope. The unit is a second SolarMax II 40 filter and RichView just like the primary unit on all SolarMax II 40 Telescopes. The new unit will fit directly to the front of your existing unit, by means of an adaptor plate (sold separately).
