Binoculars for Astronomy

Once you are familiar with the basics of the night sky, you can take the next step with binoculars.
Binoculars are great for astronomy as they give a wider field of vision though they have lower magnification. They are also cheaper than telescopes.  Binoculars are portable and are easily available.

Binoculars are specified on the basis of the magnification as well as the aperture size. A bigger aperture size permits more light to enter and provides clearer images.

For instance, 8 x 40 means that the binocular has a magnifying power of 8 and an aperture size of 40.

Common specifications are 7 x 35, 8 x 40, 10 x 50, etc.

A binocular will greatly increase you reach into the sky.  It is estimated that with binoculars an astronomer can watch nearly 100,000 stars.
