The Celestron Ultima 20-60x80mm Angled Zoom Spotting Scope delivers high-contrast views through its large 80mm objective lens and versatile 20-60x magnification range. Its optical system provides a linear field of view as wide as 105 feet at 1000 yards, and the generous 18mm of eye relief ensures comfortable viewing for all users, even with eyeglasses. The entire assembly weighs 57 oz and is fully waterproof for reliable use in any environment.
The key to the Ultima's performance is its 80mm refractor objective, which gathers over 50% more light than a 65mm model, translating to significantly brighter and clearer images, especially in low-light conditions at dawn or dusk. The light path utilizes high-grade BaK-4 prisms and is fully multi-coated to maximize transmission and contrast, reducing internal reflections and delivering sharp, true-to-color views of distant subjects.
The included zoom eyepiece provides a continuous magnification range from 20x to 60x, allowing you to adapt your view instantly. At 20x, you get a wide 2.0° angular field of view (105 ft at 1000 yards) perfect for scanning landscapes or locating wildlife. As you increase magnification to 60x, you can zoom in on fine details, like the markings on a bird or groupings on a distant target, with a focused 1.0° field of view.
Designed for the field, the Ultima 80mm is fully waterproof and nitrogen-purged to prevent internal fogging during temperature changes. The rugged, rubber-armored housing protects the optics from bumps and allows for quiet handling. The 45° angled eyepiece provides a more comfortable viewing position for extended periods, especially when observing objects at a high angle, while the 18mm of eye relief allows eyeglass wearers to see the entire field of view without removing their glasses.
The 45° angled eyepiece design of the Ultima 80mm provides a more ergonomic and comfortable viewing posture, especially for prolonged sessions or when viewing subjects at a high elevation, like birds in a tall tree or astronomical objects. It also allows for the use of a shorter, more stable tripod compared to a straight-through scope.
Yes. With 18mm of eye relief, most users who wear eyeglasses can see the entire field of view from edge to edge without having to remove them. This is a significant comfort feature for extended observation.
The Ultima 80mm is an excellent choice for this scenario. You can use the 20x magnification to scan the landscape and locate an animal, then smoothly zoom in to 60x to observe fine details like antler points on a deer or feather patterns on a hawk. The 80mm objective lens will provide a bright image even in the early morning or late evening light when wildlife is most active.
Yes. The included zoom eyepiece features an integrated T-adapter. To attach a DSLR or mirrorless camera, you simply need a T-Ring specific to your camera's lens mount. This setup allows you to take high-magnification photos, a practice known as digiscoping.
BaK-4 is a high-quality optical glass used in the prism system that corrects the orientation of the image. Compared to lower-quality glass, BaK-4 prisms provide higher light transmission and a rounder exit pupil, which results in a brighter, sharper image with better edge-to-edge clarity.
The close focus distance for this spotting scope is 26.2 feet (8 meters). This allows you to observe subjects that are relatively nearby, such as birds at a backyard feeder, with high magnification and detail.
