Product Description

Amazon.com Product Description

When it's time to gaze at the stars or take in some long-distance or low-light terrain viewing, look no further than the Celestron 71018 SkyMaster 20 x 80 binoculars. Featuring high quality BAK-4 prisms, multi-coated optics for enhanced contrast, a diopter adjustment for fine focusing, and large apertures, these binoculars offer phenomenal performance.

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.

Great binoculars, perfect for multiple uses.

Good Points:
- Great value for the money.
- good quality, great alignment
- easy to use, much more portable than a telescope (and you get to use both eyes too).
- 20x power really brings things in close.
- work great for daytime observing as well as astronomical use.

Watch out for:
- as with any high powered binocular, these really magnify your motions making things appear jittery. You need to be steady or lean against something to get a clear view.
- you will want a tripod for most critical uses
- they are heavy, so if you hand-hold them, your arms will get tired fast.

I wanted to correct some bad information said in another review. the exit pupil needed by a person is a different size based upon age. An exit pupil of 7 is more for younger people. When you age and are about 50 or older an exit pupil of 4 is exactly what you want.

I got these at a local optics store. They are fantastic, just a little heavy. When the moon is dark, and it is clear, I can get a really great view of the Beehive Cluster and a whole bunch of other Messier objects that are difficult to see in a telescope. I lie down and look straight up at the sky with them. Some star colors really jump out, yellows and reds.
