Celestron Regal M2 100ED Spotting Scope with Zoom Eyepiece for Long-Range Birding and Outdoor Activities, Featuring a Rotating Tripod Mount, Phase and Dielectric Coated BaK-4 Prisms, Plus Fully Multi-Coated Optics
Product Description
Overview
The Celestron Regal M2 100ED Spotting Scope is built for observers who need a reliable, compact instrument for extended viewing sessions. Designed around a 100‑mm objective lens, the scope balances light gathering ability with portability, making it a practical choice for birdwatching trips, wildlife observation, or general outdoor exploration.
Optical System
At the core of the scope is a pair of BaK‑4 prisms that provide a clear, distortion‑free image path. The prisms are both phase and dielectric coated, reducing internal reflections and enhancing light transmission through every stage of the optical train. The overall optical design is fully multi‑coated, meaning each lens surface has a coating that minimizes glare and maximizes light output, which helps maintain image brightness and color fidelity across the field of view.
Zoom Eyepiece
A dedicated zoom eyepiece is integrated into the system, offering a range of magnification settings that can be adjusted without changing external attachments. The zoom function allows users to transition quickly from a wide view to a detailed look at a distant target, providing flexibility for spotting birds at varying distances.
Mount and Stabilization
The scope features a rotating tripod mount, which can be positioned on a standard tripod and then rotated to align the line of sight with the subject. This rotation capability gives observers the ability to adjust the scope’s orientation while keeping the optical axis stable, which can be useful in uneven terrain or when tracking moving subjects.
Multi‑Coated Optics
All optical surfaces in the scope are fully multi‑coated. This coating strategy is applied to every lens and prism surface, helping to reduce stray light and internal reflections. The result is a clearer, brighter image, especially in bright daylight conditions. The multi‑coating also improves durability by providing a protective layer against environmental factors.
Use Scenarios
Ideal for long‑range birding, the scope’s 100‑mm objective lens delivers a balanced combination of brightness and reach. Its compact form factor makes it easy to carry on hikes, during field surveys, or while attending wildlife events. The scope’s features also support broader outdoor activities such as landscape observation, wildlife monitoring, or simply enjoying a panoramic view from a scenic location.
Design Details
The instrument is constructed with a durable metal body that resists corrosion and supports stable use in a variety of outdoor settings. The rotating mount is engineered to lock securely in place, providing reliable positioning once the desired angle is set. The zoom eyepiece is mounted on a smooth, threaded assembly that allows for precise adjustment to the target focal length.
