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.
