Stargazing Essential Kit – Binoculars

Binos

Q. What’s the single best piece of astronomy equipment you can own, whether on a budget or not?

A. Without any shadow of a doubt…..Binoculars!

Portable, light weight, robust and with plenty of daylight applications, a good pair of low or medium power binoculars is probably the single best investment you can make for stargazing or astronomy.

Unaided your eyes can potentially pick out between 5000-7000 stars from a dark site. With a good pair of medium powered binoculars that figure jumps to a staggering 600,000 stars!

Although binoculars don’t give you the huge magnifications that telescopes do they make up for that with stunning wide field views of star fields and clusters. Objects like the Pleiades, the Perseus double cluster, Orion’s nebula, the Hyades, Comets, the Andromeda galaxy and the Moon look incredible through binoculars.

They’re also perfect for the rapidly changing weather in the Highlands. During less settled conditions you can grab your binoculars and head outside for short bursts of observing, avoiding the pain of setting up and packing away a large telescope.

If buying binoculars for the first time, my advice is to avoid big astro binoculars with large objective lenses. These have their applications but usually provide poor shaky views unless adequately mounted. And once you start mounting binos you might as well get a telescope out.

Here are the three standard sizes of binocular I suggest for grab and go stargazing, with 8x40s being by preferred size in most situations:

7x35s Star reach: 450,000 Fov: 9.3
8x42s Star reach: 600,000 Fov: 8
10x50s Star reach: 750,000 Fov: 6.8
