The UpClose G2 10x25 Roof Monocular from Celestron offers the higher magnification of 10 power and the light transmission ability of 25 millimeter objectives. This makes for a lightweight monocular of only 4 ounces with a still very manageable size of 4½ inches without losing the extra up-close ability.
The near focus is 26 feet (8m) allowing quick detailed views of that unexpected flyby. A water resistant, stylish, rubber covered, aluminum housing puts strength and protection of the optic as a prime priority.
Thumb indents and finger ridges secure the grip when the last thing wanted is a dropped monocular. Drop it in the back pack, carry bag or coat pocket, but don't leave home without it.
