These Celestron SkyMaster Pro 20x80 binoculars are fantastic for stargazing, offering superb magnification and image quality and excellent low-light performance. This deal includes a tripod adapter and carrying case, since as impressive as these are they're too bulky to fit into a pocket.

In our review of the Celestron SkyMaster Pro 20x80, we said they were "Perfect for astronomy or low light use thanks to their whopping 80mm objective lenses and 20x magnification" and we stand by that. We think these are the best binoculars for stargazing.

They're also waterproof and extremely well built. We wouldn't recommend dropping them on your foot, due to their weight, but they'd no doubt survive the fall. They're absolutely brilliant for lunar viewing and offer great views of the night skies. And at this price, they're an even better deal for skywatchers.


Key features: Magnification: 20x. Objective diameter: 80mm. Field of view at 1000m: 56m. Closest focusing distance: 20.2m / 66ft. Weight: 2.45 kg / 86.4 oz. Dimensions: 330 x 241 x 102mm / 13 x 9.5 x 4 in

Price history: $245.69 is the lowest the binoculars have been in six months. They did dip to $230 in March and April, but this still beats out both Walmart and Celestron's own prices.

Price comparison: Amazon: $245.69 | Walmart: $319.95 | Celestron $319.95

Reviews consensus: We were seriously impressed by these binoculars' image quality and low-light performance. They're larger than some other binoculars, but their sheer quality requires a little extra heft. Amazon's reviews echo this sentiment; purchasers are extremely happy with their purchase, but a few suggest using a tripod.
