The CEMAX 18mm H-Alpha Solar Eyepiece from Coronado is designed with optical coatings that are specifically engineered to enhance contrast and minimize glare, and also affords excellent contrast for planetary viewing. CEMAX eyepieces are not filters and offer no protection during solar viewing, so they must be used in conjunction with a complete SolarMax filter system when observing the Sun.
It is outfitted with the common 1.25" diameter barrel to fit most eyepiece holders and accessories, and a fold-down rubber eyecup for use with or without eyewear. The 52° field of view offers a generous amount of visible area whether viewing during the day or at night.
