Overview
The 52334-CGL is a spotting scope from Celestron built around a 100mm objective lens, the kind of aperture used for long-distance target viewing, birdwatching, and astronomy on the ground.
A 100mm objective is large for a spotting scope, which typically means more light-gathering ability for dawn and dusk viewing at the cost of extra bulk. Focus is manual, so there's no motor or electronic assist for dialing in distant subjects.
- 100 mm objective lens
- Manual focus
- 22.3 x 4.6 x 4.6 in body
- Celestron brand
Who it's for
Buyers who spend time glassing long distances, whether at the range, on a mountainside, or watching wildlife, and who want a bigger objective lens than a standard 60 to 80mm scope. Less suited to anyone wanting a compact, packable option.
Pros and cons
- Large 100mm objective for more light-gathering
- Manual focus keeps the mechanism simple
- Sizable footprint at over 22 inches long
Performance notes
The 100mm objective lens is the scope's defining feature, gathering more light than smaller spotting scopes for better clarity in dim conditions. Manual focus means the user adjusts sharpness by hand rather than relying on autofocus, which is standard for this class of optic.
