Coronado 25 mm 1.25" CEMAX H-Alpha Contrast Enhanced Eyepiece

As a leader in the solar astronomy industry, Coronado takes great care in crafting each solar filter as well as all of their accessories. When producing their accessories, Coronado seeks to increase contrast by minimizing the number of components while 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.

Joseph ★★★★★

I can finally see solar prominences clearly without that annoying chromatic fringing—the contrast enhancement on this eyepiece really does make a difference. The 25 mm focal length gives a nice comfortable view that’s easy on the eye too.

Ruby P. ★★★★★

The contrast on sunspots is noticeably sharper than with my standard eyepieces, and the 25 mm focal length gives a comfortable full-disk view. I can finally see the subtle surface details that were always just a blur before.

Jason ★★★★★

The contrast on the solar surface is incredible with this eyepiece; I spotted granular details I’ve never seen before with my standard one. It’s noticeably sharper than my other 25mm, and the 1.25" size fits perfectly in my scope. I’ve spent the last two clear mornings glued to it.
