Coronado - Eyepieces

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.
