EclipSmart solar products feature Solar Safe filter technology—the ultimate protection from harmful solar radiation, including IR and UV light, plus 99.999% of visible light. Celestron Solar Safe filter technology is SAFE for direct observation of the Sun and has been independently tested to conform to and meet the transmission requirements of ISO 12312-2:2015(E), Filters for Direct Observation of the Sun, EN 1836:2005 + A1:2007 (E) for an E15 Filter for the Direct Observation of the Sun and AS/NZS 1338.1:2012, Filters for Eye Protectors.

Important safety note: inspect your filter before every use. Do not use and discard if damaged, torn, punctured, or separated from the frame in any way.


Upcoming Eclipses

2023 - On October 14, 2023, the famed “Ring of Fire” will encircle a darkened Moon during a spectacular annular eclipse.  This special type of partial solar eclipse occurs when the Moon is too far from Earth to cover the Sun completely. The Sun's corona is not visible during an annular eclipse. Click here for more info.

2024 - On April 8, 2024, the Moon will completely cover the Sun during an awe-inspiring Total Solar Eclipse. Observers within the path of totality will witness the sun’s dazzling corona, observe the “diamond ring” effect, and see day turn to night. Click here for more info.

Solar Warning
  • Only observe the Sun with ISO-compliant eye protection, such as the filter found in this EclipSmart product. Never look directly at the Sun with the naked eye or a non-filtered optic. Permanent and irreversible eye damage may result.
  • Never tamper with or remove the permanently placed glass filters in this optic. Doing so is dangerous and will void your warranty.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with its correct operating procedures is with your optic at all times, especially when children are present.
  • Never remove your eye protection when looking directly at the Sun during partial phases of a solar eclipse.
