Every stargazer needs a pair of binoculars. Unlike most telescopes, binoculars are easy and intuitive to use.  They produce a right-side-up image and a large field of view, which makes it easy to aim them at an object and find what you’re looking for. And they don’t need any time to set-up and align. You just grab them and head outside under the stars. Binoculars are especially useful for seeing large craters on the Moon, the moons of Jupiter, the occasional comet, close groupings of the Moon and planets at sunrise and sunset, and, once you know how to find them, larger star clusters and groupings of stars all over the sky. In this article, you learn how to choose and use a reasonably-priced pair of binoculars for astronomy [Read more…] about How to Choose Astronomy Binoculars

While Galileo’s profound discoveries with his first telescope in 1609 are rightly celebrated in the annals of science, the optical design of his first telescope is not. Based on a simple convex objective lens and a concave eyepiece, Galileo’s early telescopes gave drinking-straw-narrow fields of view and and image brightness that dropped off drastically at the edge. His design was quickly replaced by the so-called Keplerian telescope which we all use today. So imagine my surprise when I discovered a relatively new set of binoculars from Vixen Optics that are based on a modern version of Galileo’s original telescope design. These Vixen SG 2.1×42 binoculars, which magnify just 2.1 times and have objective lenses 42 mm diameter, give extraordinary wide-field views of entire constellations, and some say that observing with these binoculars is like having ‘super vision’ [Read more…] about Vixen’s Astonishing SG 2.1×42 Wide-Field Binoculars
