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 at
H-Alpha and multi coated on every surface (including cemented
surfaces), the CEMAX eyepieces are the ultimate in contrast
enhancement for the solar observer.
