In the construction of solar filters and associated instrumentation, Coronado takes enormous care to optimize contrast by minimizing the number of components and designing them so that they do not result in creating residual reflections and spurious light near the image. Until recently, the only component not included in this overall approach was the eyepiece. Now, the new CEMAX (Contrast Enhanced) series eyepiece fills this need. Specifically designed for use with H-Alpha filters and multi coated on every surface (including cemented surfaces.) The CEMAX eyepieces are the ultimate in contrast enhancement for the solar observer. Many users have commented that the CEMAX also afford excellent contrast for planetary viewing.
***NOTE: THE CEMAX EYEPIECES ARE NOT FILTERS AND, FOR SOLAR OBSERVING, MUST BE USED IN CONJUNCTION WITH A SAFE SOLAR FILTER.****
