  • Celestron Nature 10x25 Monocular

    The Celestron Nature 10x25 Monocular packs powerful 10x magnification and a 25mm objective lens into a compact, 6 oz chassis designed for grab-and-go observation. It delivers a generous 5.8° angular field of view and features 14mm of eye relief, ensuring comfortable, full-field viewing even for eyeglass wearers.

    10x Magnification and BaK-4 Prisms in a 25mm Optic

    The optical system is built to bring distant subjects into sharp focus. The 10x magnification provides the power needed to see detail on birds or performers from a distance, while the 25mm objective lens gathers enough light for clear, bright images in daytime conditions. Multi-coated lenses and high-quality BaK-4 prisms maximize light transmission and contrast, preventing the washed-out views common in lesser compact optics.

    Field-Ready Design at Just 6 oz and 112mm Long

    Engineered for portability and durability, the Nature 10x25 weighs a mere 6 oz and measures just 112mm in length, making it easy to slip into a pocket or pack. The chassis is fully waterproof and nitrogen-purged, protecting the internal optics from rain, humidity, and sudden temperature changes that cause fogging. Its rubber-armored body and intelligently placed focus dial allow for secure, comfortable one-handed operation in any weather.

    14mm Eye Relief for Full-Field Views With or Without Eyeglasses

    A key feature for comfortable viewing is the monocular's 14mm of eye relief, which allows you to hold the eyepiece at a comfortable distance from your eye without losing any of the scene. This is especially critical for eyeglass wearers, who can see the entire 5.8° field of view without needing to remove their glasses. A twist-up eyecup further aids in finding the perfect eye position, blocking stray light and improving image contrast.

  • What are the advantages of the Nature 10x25 Monocular over a traditional binocular?

    The primary advantage is its compact size and low weight. At just 6 oz (170.1 g) and 112mm long, the Nature 10x25 Monocular fits easily into a jacket pocket or small bag, making it ideal for hiking, concerts, or sporting events where you don't want the bulk of a full-size binocular.

    Are the optics on the Celestron Nature 10x25 good for low-light or night use?

    This monocular is optimized for daytime use. With a 2.5mm exit pupil and a relative brightness of 6.3, it delivers bright, crisp images in daylight or well-lit environments. It is not designed for astronomical observation or use in deep twilight, where a larger objective lens and exit pupil would be required.

    How close can I focus with the Nature 10x25 Monocular for watching butterflies?

    The Celestron Nature 10x25 has a close focus distance of 18 ft (5.48 m). This allows you to get detailed, magnified views of nearby subjects like butterflies, insects, or museum exhibits, provided you are at least 18 feet away.

    Is the 14mm eye relief on the Nature 10x25 Monocular enough to see the whole view with my glasses on?

    Yes. The 14mm of eye relief is generally sufficient for most eyeglass wearers to see the entire 5.8° field of view comfortably. The included twist-up eyecup helps you set the proper distance between your glasses and the eyepiece lens for optimal viewing.

    Can I use the Celestron Nature 10x25 Monocular in the rain?

    Absolutely. The monocular is rated as Waterproof and is Nitrogen Filled. This means it is fully sealed against the elements and the internal optics will not fog up due to humidity or rapid temperature changes, making it a reliable tool for outdoor adventures in any weather.

    What is the field of view of the Nature 10x25 Monocular like at a sporting event?

    The linear field of view is 304 ft at 1000 yards. This means if you were looking at a football field from 100 yards away, you would see a 30.4 ft wide section of the field. This is a generous field for following action across a wide area while still benefiting from the 10x magnification.
