Spotting Scope Celestron Ultima 80-45° BaK-4 Grey 80mm

The Celestron Ultima 80-45° BaK-4 Grey 80mm spotting scope is a compact refractor designed for outdoor observation. It features an 80 mm objective lens, multi-coated optics and a BaK-4 prism to deliver clear, high-contrast images. The scope includes a 20–60x zoom eyepiece and a 45° angled viewing tube for comfortable long sessions. With a waterproof construction, a green rubber-coated optical tube and a soft carrying case, this spotting scope is suited for nature observation, birdwatching and long-distance spotting in varied weather conditions.

Advantages

The larger 80 mm aperture provides approximately 50% brighter images than smaller 65 mm models, improving detail and visibility at higher magnifications. Multi-coated optics and a BaK-4 prism enhance light transmission and contrast for clearer images across the zoom range. The 45° viewing angle and included 20–60x zoom eyepiece increase user comfort and framing flexibility. The unit is waterproof and comes with a soft carrying case for transport and protection.

Suitable for

• Birdwatching in forests, wetlands and coastal areas
• Wildlife observation and nature study

How to use

Mount the spotting scope on a compatible tripod for stable viewing. Start with the eyepiece set to low magnification (20x) to locate your subject using the sight tube or the wide field of view, then slowly increase magnification up to 60x for detailed observation. Adjust the focus ring until the image is sharp. Use the 45° angled eyepiece to reduce neck strain during prolonged sessions and rotate the eyepiece or body as needed to frame the subject.

Usage recommendations

For best results, allow the scope to thermally adapt to outdoor temperatures before high-magnification viewing, and use a sturdy tripod to minimise vibrations. Clean the multi-coated lenses with a soft brush and lens cloth; avoid harsh solvents. The waterproof housing allows use in wet conditions, but store the scope in the soft carrying case when not in use to protect the finish and optics.
