It depends.  Just about any binoculars provide good view.  Make certain you stay away from very strong magnifications, otherwise you will need a tripod to keep them steady and may get dizzy without it.  The larger magnifications also limit your field of view.  \n\nI have some 8x42 Nikons that are great.  \n\nJust in case you are not aware:  the first number given in the binocular is the magnification.  Stick with 7 or 8.  The 10s you will need the stabilization electronics or a mono/tripod.  \n\nThe second number provides information on how much light comes through the lens.  \n\nFor example...if you were to compare the same brand and model with the exception of the number difference: 8x25 vs 8x42:  \n\nThe 8x25 will provide the same size image but the 8x42 will provide a brighter image.   If you are thinking about purchasing online...before you do find a camera store or a sporting goods store to see how they feel and get a better feel for what you really want.  Hope that helps...happy star viewing!\n\nAlso another possible source for help would be to see if there is a local star party group in your area.  Drop by one night; it can be fun to meet some experienced viewers with telescopes already setup as well as some people who have the really large expensive scopes which you may not be able to afford.

Bald Eagles are thought to have the best eyesight of any animal, having up to eight times the resolving power of the human eye. The retina has two focusing foveae (human eyes have only one) which allows them to use both eyes together (binocular vision like humans) for telescopic viewing, or each eye independently (monocular vision) for up close viewing. They see in color.

The Bradford telescope at the website below is the best:\n\nhttp://www.telescope.org/

www.opticsplanet.com has decent section on birding binoculars, and what to look for them.  Bear in mind they are a retailer, looking to make a sale.\n\nI have purchased from them before, and they have a pretty good reputation.

A good mid-priced porro-prism binocular such as the Orion Vista will be good enough for most people. If you want the best, look into the Nikon Prostar or Fujinon Polaris binoculars.  The Canon image-stabilized 15x50 is another good, premium astro binocular.\n\nMany of the lower-priced models from Orion, Celestron, and others will do fine. You'll get a little more distortion towards the edges of the field, and maybe a little less light throughput in the cheaper bins. For astronomy, you can dispense with extras such as rubber armor, weatherproofing, and center focus. Porro-prisms are better for astronomy than roof prisms, because the roofs can show a bit of a spike on bright stars. Avoid models with polarizing or anti-haze filters or coating - fine for daytime use, but their light throughput is considerably reduced.
