Binoculars, or possibly a Telescope? Which should I acquire first?

By Joseph Swinden


Any time you visualize an astronomer it tends to envision the image of a person which has a telescope. The will to acquire a telescope and unlock all of the glory of the heavens and its wonders is powerful to start with. But perhaps you should consider getting yourself binoculars first. Here's why.

Effective binoculars will help you view the craters upon the moon, the moons around Jupiter and in many cases make out some galaxies (which include M81 and M82 within the constellation Ursa Major).

They need to have a great field of view to enable you to better discover the constellations and surf around the stars belonging to the Milky Way. Contrary to many telescopes which invert the picture of the night sky, binoculars are orientated in the same way as you really view the sky, which assists to search out objects of great interest. Because if you realize the thing is down and left from a star you only need to point the binoculars down and left. With a telescope you need to bear in mind left is right and up is down. So, put a reclining chair in your back garden, lay down and savor exploring the evening sky.

Binoculars for astronomy must be lightweight while having an adapter to fit them to a tripod. The reason is, just one of the difficulties with binoculars is that if they are too large then you will begin to shake when keeping them up to the night sky for any length of time. This is certainly made worse by getting binoculars, which has a higher magnification because shaking is amplified too.

A good, adaptable pair of binoculars would as a rule have about a magnification of 7-10 times and lens apertures of approximately 35-50 mm (abbreviated as 10x50 for 10x magnification and 50mm aperture).

So which should you buy first, binoculars or even a telescope? Binoculars really are a less costly option and make learning the night sky an even more pleasurable experience. Sure you won't have the ability to delve straight to viewing those challenging faint deep space objects but if you don't recognize the constellations then you wouldn't locate them anyway. Of course, if you bought a Goto telescope then you definitely wouldn't need to learn the constellations, because the telescope will point you straight at the deep space target, but you'll lose out on the pleasure that having the ability to navigate the evening sky and all of its wonders brings to you when you carry on and learn astronomy.
