Don't you wish your eyes were more powerful and that you could gaze at the night sky with the naked eye and see more detail and depth? Stargazers always want a closer look, but before you invest in an expensive telescope or start browsing our best binoculars list for a pair with huge magnification, consider the unique properties of the Vixen SG 2.1x42 super-wide binoculars (US$299/US£289/AUS$385). These are the original ultra-wide binoculars that are designed not to get you a close-up of a star cluster, a nebula or the Moon, but a better wide-field view of the night sky.
However, with a mere 2.1x magnification are these unique pocket-sized binoculars really worth bothering with? Here's our full Vixen SG 2.1x42 super-wide binoculars review.
Vixen SG 2.1x42 binoculars review: Features and performance
The Vixen SG 2.1x42 are all about immersing yourself in the night sky. With 2.1x magnification, everything is magnified twice over, but no more. That's not much. They're terrible for moon gazing. You won't get a great view of nebulae, or get any kind of impressive close-up of star clusters like the Pleiades, Hyades and the Beehive (although they do make them stand out more). You also certainly won't glimpse a galaxy while using the Vixen SG 2.1x42. So what's the point of these odd-looking binoculars?

The Vixen SG 2.1x42 reveal many more stars that your naked eyes can see. Which is why the Vixen SG 2.1x42's rare wide field of view – which stretches to 25º – earn them the nicknames of 'constellation' or 'Milky Way' binoculars.
To find out why let's look at the Vixen SG 2.1x42's unusual specifications. They're rated as 2.1x42, which means they magnify everything by 2.1x and they have an objective lens with a diameter of 42mm. That latter number is about how much light they let it, and on the Vixen SG 2.1x42 it's comparable to a 'normal' pair of stargazing binoculars. That's more than can be said for the 2.1x magnification, which is all about preserving a 'wide-eyed' view of the cosmos while effectively extending your eyes' limiting magnitude (the faintest stars that your eyes can see).
The Vixen SG 2.1x42 work really well and are especially useful if you're hiking or camping in a dark sky site in summer when the Milky Way is arching across the night sky.
Their lack of magnification also has a positive unintended consequence. Binoculars with a much bigger magnification tend to give users shaky images. That's because humans are hot and constantly moving, something magnification shows up very easily. Not so on the Vixen SG 2.1x42; their lack of magnification means a super-steady and bright field of view.
The build quality of the Vixen SG 2.1x42 is exquisite. Made in Japan, their metallic chassis and bridge is reassuringly weighty without being heavy. Each eyepiece focuses individually, which is rare. They're pocket-sized and come with a nice soft carry case, as well as neck strap. In fact, if you hang them around your neck and you'll barely notice they're there at all.
However, there are two things we didn't like about the Vixen SG 2.1x42. The first was their four lens caps, which fit snugly yet are completely removable, so easy to lose. More seriously is that image quality suffers around the edges, with a constant blur around everything, which can be distracting.
Sure, they a specialist purchase, but the Vixen SG 2.1x42 are the ultimate binoculars for stargazers who don't really want much equipment and certainly don't want to buy a telescope. Constellations and the Milky Way have never looked better, and if you're learning the night sky and want to remain immersed in it, the Vixen SG 2.1x42 will give you a unique view.
