CEMAX 25mm Contrast Enhanced eyepiece. Specially designed and coated for optimizing H-alpha viewing.
In the construction of solar filters andassociated instrumentation, Coronado takes enormous care to optimize contrast byminimizing the number of components and designing them so that they do notresult in creating residual reflections and spurious light near the image. Untilrecently, the only component not included in this overall approach was theeyepiece. Now the new CEMAX (Contrast Enhanced) series eyepiece fills this need.Specifically designed for use at H-Alpha and multi coated on every surface(including cemented surfaces), the CEMAX eyepieces are the ultimate in contrastenhancement for the solar observer. THE CEMAX EYEPIECES ARE NOT FILTERS AND FOR SOLAR OBSERVING MUST BE USED IN CONJUNCTION WITH A SAFE SOLAR FILTER.Many users have commented that the CEMAX also afford excellent contrast forplanetary viewing.
