Coronado 18 mm 1.25" CEMAX H-Alpha Contrast Enhanced Eyepiece

As a leader in the solar industry, Coronado takes great care in designing each solar filter and all of their accessories. When producing their accessories, Coronado seeks to optimize contrast by minimizing the number of components and reducing residual reflections and spurious light near the image that plague many other solar filters.Until recently, the only component not included in this overall approach was the eyepiece. Now the new Coronado 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.

Customer Reviews (4.6 / 5 · 5 reviews)

Matthew K. ★★★★★

The contrast on this eyepiece really brings out surface detail on solar prominences, much more than my old generic plossl. That H-alpha coating makes the difference even in mediocre seeing conditions.

Madison X. ★★★★★

I was worried an 18mm might be too narrow for comfortable solar viewing, but the eye relief is surprisingly generous and makes long sessions easy. The contrast on prominences really pops without washing out the surrounding surface.

Julian ★★★★★

The contrast boost on sunspots is immediately obvious—even with thin haze, the granulation pops like I've never seen through a 1.25" eyepiece. Comfortable eye relief for a full disk view, and it's stayed crisp all session.
