Key Specs: Here, the magnification and power stand out. It’s a 25x magnification, making really far-off objects visible and the 100mm objective lens diameter means lots of light passes through. A rubber armor means these binoculars are durable, water resistant and comfortable. Bak-4 prisms mean you get quality optics too. 

Accessories: A carry case and tripod adaptor are the stand-outs. Both are well needed as these binoculars are sizable and it makes transporting and viewing a lot easier. 

Buy if: You’re looking for a pair of binoculars for stargazing or long-distance Earthly viewing. These are also well suited to those with more experience using binoculars. 

Don’t Buy if: You’re completely new to using binoculars or you’re only wanting a pair for bird-watching or viewing at short-to-medium distances. Also if you’re budget doesn’t quite stretch this far, there are other models that don’t quite offer the power but do come in at a lower price point. 

Alternative models: If this isn’t quite right for you, we would recommend the Celestron SkyMaster Pro 15×70 binoculars. We think they’re the best on the market for views of the moon, they’re powerful and they come in at a much lower price point.
