Celestron SkyMaster 71017
Celestron is a recognized name in telescopes, so it's no real surprise that they also make a 25x100 pair of binoculars powerful enough to see distant objects in the night sky. The SkyMaster comes with a magnification of 25 and a giant 100mm objective lens. The binoculars have individual eye piece focus and a long eye relief, great for those who wear glasses. The optics itself is multi-coated for clearer views. The binoculars weigh 140 oz, so it's advisable to get a tripod mount. If you'll be taking these binoculars with you while camping, it should be noted that the SkyMaster is waterproof, capable of withstanding some weather, and the carrying case is made out of padded nylon.
Zhumell Tachyon 25x100 Astronomy Binoculars
The Tachyon 25x100 by Zhumell is similar to the SkyMaster. They both have multi-coated lenses, and they both also have BAK-4 porro prisms, resulting in sharper images. In addition, the Tachyon has the individual eye piece focus and also an eye relief that works well for people who wear glasses. However, the Tachyon is also able to accept 1.25-inch astronomical filters that go over the eye piece. This is great for blocking out unwanted light and perfect for looking at the moon or other features of the night sky. The Zhumel Tachyon is even heavier than the SkyMaster at 164.8 oz, however they are also very rugged. The Tachyon is nitrogen-purged, making it waterproof and able to withstand being fully submerged in water, i.e. perfect if you plan to be out in the woods with these for a few days.
Orion Giant View 25x100 Astronomy Binoculars
The Orion Giant View differs very little from the SkyMaster and the Tachyon. It too has BAK-4 porro prisms, is fully multi-coated and also has the long eye relief with the individual eyepiece focus. At 10.1 pounds, it is similar in weight to the Tachyon. But unlike the Tachyon or the SkyMaster, it is not waterproof. In addition, although the barrels of the binoculars are cross-reinforced with an aluminum rod to keep the optics aligned, the Orion Giant View is not built with the same kind of durability as other 25x100 binoculars.
