SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

These eyepieces are not filters, and when used as part of a solar viewing system, they must be used in conjunction with a blocking filter and a SolarMax filter.

Coronado CEMAX 2x Barlow Lens (1.25")

The Coronado CEMAX 2x Barlow Lens doubles the magnification of any 1.25" eyepiece to increase the usability of the eyepiece without affecting exit pupil, eye relief image or overall image brightness. While it may be used for conventional nighttime astronomical observation, it has been designed primarily for use at H-alpha (Ha) wavelengths with fully multicoated optics tuned to ensure maximum contrast when used with Ha solar filters.

This Barlow lens is not a filter, and when used as part of a solar viewing system, it must be used in conjunction with a blocking filter and a SolarMax filter.

Coronado CEMAX 12mm H-Alpha Solar Eyepiece (1.25")

The CEMAX 12mm H-Alpha Solar Eyepiece from Coronado is designed with optical coatings that are specifically engineered to enhance contrast and minimize glare, and also affords excellent contrast for planetary viewing. CEMAX eyepieces are not filters and offer no protection during solar viewing, so they must be used in conjunction with a complete SolarMax filter system when observing the Sun.

It is outfitted with the common 1.25" diameter barrel to fit most eyepiece holders and accessories, and a fold-down rubber eyecup for use with or without eyewear. The 52° field of view offers a generous amount of visible area whether viewing during the day or at night.
