Although the Canon line of image-stabilized binoculars (reviewed here) is the most comprehensive, there are other manufacturers making similar products. The one that I most often get e-mail requests to evaluate are the Fujinon 14×40 Techno-Stabi binoculars. Little wonder — Fujinon is a highly regarded manufacturer popular with backyard astronomers.

Early summer is a great time to use binoculars to view a real odd couple: M4 and M80 in Scorpius. As the image above suggests, both globular clusters can be located by keying off golden Antares. That’s why I refer to them as “Antares Globulars.” Use the trio of images presented here to hunt them down.

A bewildering assortment of binoculars awaits at your local camera store. But when it comes to stargazing, some binos are better than others.
Binoculars come in a dazzling variety of magnifications and sizes. Many stargazers recommend 10x50s — binoculars that magnify 10x and have 50-millimeter-diameter objective lenses.

But is this actually true, and more importantly, should it factor into your binocular selection?

Build this simple device for steady binocular views of the night sky.
I love binocular astronomy. At least, that’s my excuse for cluttering the house with a dozen (at last count) of these double-barreled optical wonders. Recently, my collection expanded to include particularly heavy 10×50s and inexpensive 15×70s. For the first time I really felt that I needed some kind of binocular support.

Choosing binoculars is easy once you understand the specs.
Shopping for binoculars at your local camera store or on-line can be a bewildering experience. And if stargazing is your goal, the task becomes even more confusing — there are so many factors to consider and so many (often contradictory) opinions about what matters and what doesn’t. Fortunately, once you understand some of the basic specifications, figuring out whether or not a given binocular is going to suit your needs becomes a lot easier.
