There is a great number of astronomical binoculars for sale from all the popular brands,Barska, Bushnell, Celestron, Meade, Orion, Skywatcher,Tasco, Zhumell and many others. A lot of people mistakenly think that astronomical binoculars just can't possibly be as good as a telescope as they don't magnify sufficiently.
It is a fact that binoculars for astronomy will only magnify 10 to 35 times at best, which is insufficient to show fine detail on planets, however, the limited magnification and light gathering power is more than enough to locate many of the sky's most amazing and intriguing celestial objects.
Generally a good pair of 10x50 binoculars are more than adequate for the majority of people, any larger and you will probably need a tripod for support as they can get to be rather heavy if held for a some time. If you intend buying a larger pair something such as 25x70 or greater just make sure it has provision to take a tripod.
Binoculars are widely used by amateur astronomers all around the world because of their convenience and portability. Astronomy binoculars have a wide field of view which makes them a good choice for comet and supernova seeking as well as general observation.
