A Coronado eyepiece can complement and enhance views through your solar telescope. The revolutionary Coronado Personal Solar Telescope is the most popular solar telescope in the world, but you still need to make sure your eyes are protected when looking at a solar eclipse, solar flare, or other solar phenomena. Outfitting your solar scope with a Coronado eyepiece is a safe and easy way to experience the joy of viewing the Sun.


Coronado’s CEMAX H-Alpha eyepieces fill this need for protection and enhanced Sun observations. 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. Whether you choose the 12mm, 18mm, or 25mm eyepiece, rest assured that your eyes will be protected from the Sun’s harmful rays with their multi-coated, H-Alpha enhanced optics. Each eyepiece has a 52° apparent field of view and a generous 20mm of eye relief. These features give observers a comfortable, immersive experience that you can enjoy for years to come.


Proper eye protection is about more than just the equipment you use. Sun observer also need to take extra precautions in order to avoid permanent eye damage. Before viewing, always inspect your solar equipment and do not use if there are any scratches or damages on the optics. Never look at the Sun without proper eye protection. When using a solar telescope, look into the scope while it is pointed away from the Sun. Then, while your eye is in the eyepiece, slowly point the solar telescope towards the Sun. Once the scope is focused properly, close your eyes before taking your eye out of the eyepiece and close your eyes before placing your eye in the eyepiece. We also recommend you use a shroud to protect your head, neck, and non-observing eye from the Sun’s rays.
