The 15x70 designation is the whole argument for the SkyMaster: 70mm objective lenses gather enough light to pull star clusters and the Orion Nebula out of the sky, while 15x is enough magnification to make the moon's craters look like terrain rather than smudges. We think it is the best first serious astronomy binocular for most people because it delivers that combination without moving into the large, heavy classes.
The 4.4-degree field is a useful middle ground. It is wide enough to scan along the Milky Way and locate constellations, but not so wide that everything collapses into a tiny, cluttered view. We also appreciated the 18mm eye relief, which gives glasses wearers a reasonable chance of seeing the full field without pressing into the lenses. The center focus is smooth and easy to settle, and the rubber-armored body feels secure in the hand.
At 3.3 pounds, the SkyMaster is not a binocular for a long hike or a quick look out the window. Handheld, the view swims after a few seconds at 15x, especially when you are trying to study a small target. Mount it on a sturdy tripod and the instrument makes sense: the built-in 1/4-inch-20 adapter is there, but the tripod is not. A lightweight photo tripod will fight you; use something with a rated load well above the binoculars.
The glass is multi-coated BaK-4, and the housing is water-resistant rather than waterproof. For a backyard astronomy pair, that is a sensible place to save. We kept coming back to the same conclusion: this is the pair that makes the night sky accessible without a telescope, as long as you give it a proper mount.
Pros
- 70mm aperture for bright deep-sky views
- 15x magnification reveals lunar detail
- 18mm eye relief suits glasses
- Good value for the aperture
Cons
- Tripod required but not included
- Heavy for handheld use
We recommend the SkyMaster 15x70 as the best all-around astronomy binocular for its balance of light grasp, lunar detail, and price.
