The UpClose G2 10-30x50 Zoom Porro Binoculars from Celestron are large handheld binoculars with a very welcome integrated tripod thread. The 50-millimeter objectives are bountiful light gatherers allowing for bright images during low-light conditions such as dawn, dusk, and overcast days. The expansive zoom magnification sharpens the details as the subject is enlarged from the expansive scan of 10x to the minuscule precision of 30x. These are powerful binoculars that are just over the line of handheld practicality. Any support will come in handy; such as a car top, a fence, a tree, or the mast stay of a boat unless of course they are being leveraged with a tripod. Besides their all around usefulness for just about any application, their large aperture and high magnification are also suited for astronomical observation.
A very welcomed Apparent Angle of View (AAoV) stretches past 65 degrees at 30x power. BAK7 glass with multi-coated optics dispenses brighter, sharper, higher contrasted images. The housing is water resistant, rubber coated, and made out of aluminum. There are ergonomic thumb indents and finger ridges for a firm, slip-proof grip even in inclement weather conditions. The large center focus knob will be especially appreciated in challenging, high-stress situations. A dioptric ring adjuster and fold down rubber eyecups customize the comfort level to individual preferences. The built-in tripod threaded screw hole is located underneath a protective cap. Use of a tripod allows for added stability and comfort especially when viewing at high powers.
