CEMAX 2x Contrast Enhanced barlow. Specially designed and coated for optimizing H-alpha viewing.

In the construction of solar filters and associated instrumentation, Coronado takes enormous care to optimize contast 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 now, the only component not included in this overall approach was the eyepiece. Now the new CEMAX series fills this need. Specifically designed for use at H-alpha and multicoated on every suface (including cemented surfaces), the CEMAX eyepieces are the ultimate in contrast enhancement for the solar observer.
