Your card will only be charged once item ships.
The CEMAX (Contrast Enhanced) series eyepieces, specially designed and coated for optimizing H-Alpha viewing. These Eyepieces are not HA filters and for solar observing they must be used in conjunction with a safe solar filter.
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 now, the only component not included in this overall approach was the eyepiece. Now the CEMAX SERIES 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.
