Where To Buy?
The Coronado CEMAX 1.25" 18mm 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 general astronomy. 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 12 and 25mm eyepieces, meaning there will be minimal focus shift when changing between eyepieces. Features 11mm eye relief, a 52° apparent field of view, and includes a foldable rubber eye guard.
CAUTION: Never look through a telescope at the sun without either using a dedicated Hydrogen-Alpha telescope with built in etalon and blocking filters, or a professionally made white light solar filer that completely covers the front of the instrument. Otherwise permanent eye damage could result.
Please note this product was not designed or intended by the manufacturer for use by a child 12 years of age or younger.
