Celestron Ultima 65 - 45 Degree Spotting Scope

18-55x Zoom and 65mm Fully Multi-Coated Optics

The heart of the Ultima 65mm is its flexible optical system, designed for a wide range of field applications. The 18-55x zoom eyepiece lets you scan a wide area at low power, then smoothly magnify your subject for a closer look without changing eyepieces. The 65mm objective lens gathers ample light for clear, bright images, especially during the critical dawn and dusk hours when wildlife is most active.

• Fully Multi-Coated Lenses: Every air-to-glass surface is treated with multiple layers of anti-reflective coatings to maximize light transmission and contrast, reducing glare for sharper views.
• BaK-4 Prisms: This higher-quality prism glass minimizes internal light scattering and produces a perfectly round exit pupil, resulting in a brighter, more color-faithful image compared to scopes with BK7 prisms.

45° Angled Viewing and 18mm of Eye Relief

Designed for sustained observation, the Ultima 65mm's ergonomics prevent user fatigue. The 45° angled eyepiece is ideal for viewing objects at various elevations, from birds in treetops to targets on a range, without requiring you to crane your neck. This setup is also more comfortable for sharing views with a group, as it allows for a lower, more stable tripod height.

With 18mm of eye relief, this spotting scope is comfortable for all users, including those who wear glasses. You can see the entire field of view without needing to press your eye against the eyepiece, a critical feature for long sessions of spotting or birdwatching.

Waterproof, Nitrogen-Purged, and Weighing only 37 oz

The Ultima 65mm is built to withstand the elements. Its housing is fully waterproof to protect the optics from rain, mist, or accidental immersion. The optical tube is also purged with dry nitrogen gas, which prevents the internal lenses from fogging up during rapid temperature or humidity changes—a common issue when moving from a warm car to the cold outdoors.

At just 37 oz (1049 g), this scope is light enough to be carried on long hikes without becoming a burden. The subtle green rubber armoring provides a secure grip while helping it blend into natural surroundings for discreet observation.

Ultima 65mm vs. Larger Models: The Portability Advantage

While larger spotting scopes like the Ultima 80mm or 100mm offer brighter images due to their larger objectives, the 65mm model holds a distinct advantage in portability. Its lower weight and smaller dimensions make it the superior choice for observers who prioritize mobility.

• For the Hiker: If your observation spot is miles down a trail, the compact size and 37 oz weight of the 65mm are far more practical than a larger, heavier scope.
• For the Traveler: The Ultima 65mm packs easily into luggage or a backpack, making it an ideal companion for any outdoor enthusiast on the go.

The choice comes down to your primary use case. For backcountry observation where every ounce matters, the Ultima 65mm delivers excellent optical performance in a package that won't slow you down.
