  • More Info
    • 12mm focal length 1.25" eyepiece for a medium-high powered view, depending on the telescope focal length
    • Specifically designed for use at H-alpha wavelengths in order to enhance contrast of solar features
    • Provides a 52-degree field of view and 8mm eye-relief

    • Threaded for standard 1.25" filters, and includes caps and a rubber eye guard for comfortable viewing

    The Coronado CEMAX 1.25" 12mm Eyepiece is designed specifically for enhanced solar contrast when used with Coronado H-alpha Solar Telescopes and filters. Optimized coatings are used to enhance contrast at H-alpha (H-α) wavelengths and to minimize glare when viewing the solar disk and limb. Additionally, this eyepiece performs extremely well at night for lunar and planetary viewing. Includes caps for both ends to protect the eyepiece from dirt and debris when stored away.

    Please note that this eyepiece is NOT a filter itself and for solar observing MUST be used in conjunction with a Coronado Ha Solar Telescope or telescope with a Coronado filter set properly installed.

    Parfocal with the CEMAX 18 and 25mm eyepieces, meaning there will be minimal focus shift when changing between eyepieces. Features 8mm eye relief, a 52 apparent field of view, and includes a foldable rubber eye guard.
