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 Limited Lifetime Warranty.

However I asked if I could collimate it myself even though the manual says it should only be done by a professional with specialized tools. They could not or would…
Fine for the price. The reviews to date told me pretty fairly what to expect. I already have a tripod, and these binoculars are fun to use.
Very nice binoculars ! Just saw the conjunction of Mars and Jupiter (1/6/18,5:30CST). I could see four of Jupiterâs moons. The red color of Mars along side of the white Jupiter (you canât see any stripes) was awesome. You need a tripod for these big and heavy binoculars unless you lay back on a lawn chair (to view directly overhead). I wear glasses and have no problem looking through the binoculars. They wonât replace a telescope since the magnification is 20X, but theyâre great for quick set up and imaging of the…
