Celestron Hummingbird 9-27x56mm ED Micro Spotting Scope

56mm ED Optics: Color-Fringe-Free Views

The heart of the Hummingbird is its 56mm objective lens, crafted from high-quality Extra-Low Dispersion (ED) glass. This isn't just a marketing term; ED glass virtually eliminates chromatic aberration, the color fringing visible on high-contrast edges in standard optics. This results in razor-sharp images with true-to-life color, especially critical when identifying subtle plumage details at dawn or dusk.

• Fully Multi-Coated Lenses: Every air-to-glass surface is coated to maximize light transmission, delivering brighter images and improving contrast.
• Phase-Coated BaK-4 Prisms: The high-grade BaK-4 prisms are phase-coated, a step often omitted in lesser scopes. This coating enhances resolution and contrast for a visibly sharper image across the entire field.
• Twilight Factor (22-39): The combination of aperture and magnification gives the Hummingbird a high twilight factor, quantifying its ability to resolve detail in low-light conditions.

20.8 oz Micro-Spotter: Packable and Waterproof

Designed for mobility, the Hummingbird lives up to its name with a compact form factor and a weight of only 20.8 oz (590 g). It easily fits into a pack pocket or carry-on, making it an ideal alternative to a full-sized scope for birders, hikers, and travelers. Its rugged construction ensures it can handle the rigors of field use in any environment.

The housing is fully waterproof and nitrogen-purged, preventing internal fogging of the lenses during sudden temperature changes or in humid conditions. This internal sealing protects the optics from moisture, dust, and debris, ensuring clear views no matter the weather. The durable external armor provides a secure grip and protects against bumps and jolts.

9-27x Zoom Range: From Wide-Field to High-Power Detail

The integrated eyepiece provides a seamless 9-27x zoom range, offering the versatility of a binocular and a spotting scope in one. At 9x, you get a wide 216-foot linear field of view at 1000 yards, perfect for quickly locating subjects or scanning landscapes. As you zoom to 27x, you can zero in on distant targets to resolve fine details, making it perfect for reading tags or identifying distant birds of prey.

• Smooth Zoom Control: The mechanism is designed for smooth, precise adjustments, allowing you to follow a subject and change magnification without losing your target.
• Variable Exit Pupil (6.2mm - 2mm): The exit pupil changes with magnification, providing a bright, easy-to-view image at 9x and a more detailed view at 27x.
• Tripod Adaptable: For extended viewing sessions, especially at higher magnifications, the scope can be mounted on any standard tripod, monopod, or window mount for a stable, shake-free image.
