Amateur Astronomy: Astronomy Binoculars For Beginners

By Gary Nugent

Astronomy binoculars and telescopes and other astronomy equipment and accessories are at the heart of of amateur astronomy.

What helped me familiarise myself with the night sky was a good set of binoculars. It was only after using them for a couple of years that I upgraded to a telescope.

That was one of the department store 60mm telescopes we're all warned about, but my folks didn't know any better, and to a 12-year old kid, it opened up the universe.

Good Binoculars For Astronomy

Binoculars have a role to play in astronomy. Good binoculars for astronomy cost less than a telescope and are an excellent choice for someone familiarising themselves with the night sky.

They don't provide the same magnifications as a telescope (but magnification isn't everything) but binoculars do show a much wider field of view which makes it easier to navigate across the sky.

And, since you're using both eyes, you suffer less eyestrain. You also have the added benefit of being able to see the "big" picture.

Binocular viewers are available for telescopes and those who use them (even though they cost a couple of hundred dollars and you need two eyepieces for each one) swear by them (rather than at them!). However, since these are a piece of specialised equipment, they will cost more than a pair of binoculars.

A typical set of binoculars will be 10x50s (10x magnification and front lenses 50mm in diameter). More powerful models are available - 20x60s cost from $150 upwards and you can get 20x80s for as little as $90 (yes, cheaper than 20x60s).

Astronomy binoculars are quite heavy and you can tire easily pointing them at the sky for an extended period. Also, because of their higher magnification, any shake in your hands will also be magnified and stars will bounce around in the view.

If you plan to look at the sky for extended periods, you'd be advised to use a tripod with a binocular adaptor. This lets you securely mount the astronomy binoculars on it and easily point them around the sky without strain.

Binoculars are also great for looking at large scale celestial objects such as comets. The Moon through 20x binoculars is a revelation, bringing it close enough to see topography but also, you'll see it in three dimensions, something a telescope can't do as you only look though one eyepiece instead of two.

Good astronomy binoculars for beginners are available from a wide range of manufacturers: Celestron, Meade, Zhumell, Barska, Pentax and Canon.

Serious amateur astronomers may want to invest in top-brand models from Nikon, Vixen, Kowa and Fujinon. Expect to pay $1,000 and upwards to $5,600 depending on the make and model. Why would anyone want to pay so much for a pair of binoculars? They're the best instrument for comet hunting for one. The 3-D view they give makes you feel like you're out in space. The better models use interchangeable eyepieces so you can change the magnification and field of view.

Conclusion

You can start using a pair of binoculars much more quickly than setting up a telescope so if the weather is very changeable where you live, they're probably a better option for sky watching. Naturally, binoculars go into your luggage a lot more easily when you're travelling allowing you to view the sky from your holiday destination with ease.

All in all, astronomy binoculars are a much better option for casual viewers because of their portability, usefulness for both terrestrial and astronomical observing and their cost in comparison to a decent telescope.

As with almost everything else in life, you get what you pay for. There are binoculars that cost under $10 (being cheap in every sense of the word) and other specialised astronomy binoculars which cost in excess of $5,600. My experience says you will need to spend at least $90 for a pair of binoculars that are worth having, but $140-300 is a more common price range for astronomy binoculars. - 32540
