  • Celestron EclipSmart 10x25mm Roof Solar Binoculars

    The Celestron EclipSmart 10x25mm Roof Solar Binoculars provide safe, direct solar observation with 10x magnification and 25mm objective lenses. These compact binoculars weigh only 11.46 oz and deliver a 5.7° field of view, making them the ideal grab-and-go instrument for watching an eclipse or studying sunspots. With permanently installed filters that meet the ISO 12312-2:2015(E) safety standard, you can observe the Sun with complete confidence.

    ISO 12312-2 Certified Permanent Filters

    Unlike standard binoculars that require separate, detachable filters, the EclipSmart 10x25mm has its Solar Safe filters built directly into the optical path. This permanent, non-removable design eliminates the risk of a filter being accidentally knocked off during observation. The multi-coated glass filters are certified to meet the rigorous transmission requirements of ISO 12312-2:2015(E), blocking 99.999% of visible light as well as harmful IR and UV radiation, ensuring your eyes are protected.

    10x Magnification and 5.7° Field of View

    The 10x magnification brings our closest star into sharp focus, revealing the dark umbra and lighter penumbra of sunspot groups. While providing this detailed view, the 5.7° angular field of view is wide enough to frame the entire solar disk at once, so you can watch the complete progression of an eclipse without needing to pan. The multi-coated BK7 optics produce a high-contrast and true-to-color white-light image, rendering the Sun in neutral tones against a black sky.

    11.46 oz Ultra-Compact and Water-Resistant Body

    Engineered for portability, the Celestron EclipSmart 10x25mm weighs just 11.46 oz (325 g) and measures only 114mm long. This pocket-sized form factor is protected by a rubber-armored housing that is also water-resistant for durability in the field. The folding eyecups and 10.5mm of eye relief allow for comfortable viewing for most users, while interpupillary distance can be adjusted from 56mm to 72mm to fit a wide range of observers, including children under supervision.

  • Are the EclipSmart 10x25mm binoculars safe for looking directly at the sun?

    Yes. The binoculars feature permanently installed filters that are independently tested and certified to meet the ISO 12312-2:2015(E) standard for direct solar observation. They block harmful IR and UV radiation and 99.999% of intense visible light.

    What can I see on the Sun with the EclipSmart 10x25mm?

    With 10x magnification, you can easily observe and track large sunspot groups across the solar disk. During a solar eclipse, you will see the Moon's silhouette pass in front of the Sun, and the wide 5.7° field of view allows you to see the entire event without repositioning the binoculars.

    Can I use these EclipSmart binoculars with my eyeglasses on?

    The EclipSmart 10x25mm has 10.5mm of eye relief. While this may be sufficient for some low-profile glasses, users with deeper-set eyeglasses may need to observe without them to see the full field of view. The binoculars have a ±2 diopter adjustment to help compensate for focus differences between your eyes.

    Why are the filters permanently attached to the EclipSmart 10x25mm?

    Safety is the primary reason. Detachable solar filters for standard binoculars can be accidentally knocked off or improperly installed, creating a severe risk of instant and permanent eye damage. The integrated, non-removable filters in the EclipSmart 10x25mm make such an accident impossible.

    Can I use the EclipSmart 10x25mm for regular birdwatching or stargazing?

    No. These are dedicated solar-only binoculars. The filters are extremely dark and designed exclusively for viewing the Sun. They will not transmit enough light to see terrestrial objects or nighttime celestial objects like the Moon, planets, or stars.

    How portable are the EclipSmart 10x25mm binoculars?

    They are extremely portable. Weighing only 11.46 oz (325 g) and small enough to fit in a coat pocket or purse, they are designed as a "grab-and-go" instrument for eclipses, travel, or quick daytime solar viewing sessions.
