Coronado 18mm Cemax Eyepiece

Coronado 18mm Cemax Eyepiece

Until recently, the only component not included in this overall approach was the eyepiece. Now the new CEMAX (Contrast Enhanced) series eyepiece 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.

Although designed as an eyepiece for Solar observing the Coronado Cemax range work extremely well for night time astronomy due to the high contrast design.

Customer Reviews

  Review of Cemax 18mm  I bought this eyepiece to use with my Coronado PST. It is an improvement on the 20mm eyepiece that came with the telescope and shows better contrast than any of my Celestron X-Cel eyepieces. The only downside is that in my view they are rather expensive. Excellent service from Harrison telescopes.  (17/06/2018) Erol Yusuf - Edgware, Middlesex

Coronado 18mm Cemax Eyepiece

MPN: CE18





Price: 88.00


The 18mm Cemax eyepiece is ideal for medium and lower power views of the Sun through Coronado Solar Telescopes. 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.
