Celestron SkyMaster 20x80 Binoculars Review
Celestron SkyMaster 20x80 Binoculars Feature
- Multi-coated optics for a clear view
- Water-resistant body
- High-quality BAK-4 prisms
- Large aperture perfect for low light conditions and stargazing
- Features integrated tripod adapter rod
The Celestron 71018 features a 20x magnification and an objective lens diameter of 80 millimeters, giving it a 4-millimeter exit pupil. (The exit pupil size -- the diameter of the objective lens divided by the magnification -- determines the amount of light available to your eye. The larger the exit pupil, the brighter the image obtained will be. A three-millimeter exit pupil is generally sufficient for daytime use, five-millimeters is suitable for daytime and twilight, and seven-millimeters is generally necessary for maximum nighttime or astronomy use.) The Celestron 71018 also includes an integrated tripod adapter rod, a deluxe padded soft carrying case, and Celestron's No Fault Limited Lifetime Warranty.
