A pair of binoculars can be seen as two such telescopes, side by side, which together produce an image which has the depth of field that we are used to, rather than just a large flat image. There are a lot of issues when it comes to choosing binoculars for bird watching.
Many pairs of binocualrs are not suitable for low-light conditions. When hiking or orienteering, binoculars will be very useful, but it is important to note that optics are very fragile, and so plastic lenses over glass ones, and a rugged case are probably going to be more important than high power, or the ability to use them at night. The soft or rubber fold-down eye cups will give eyeglass wearers a better view by allowing them to see the entire field.
A 7 x 50 binocular shows a view magnified 7 times and it has objective lenses 50 mm wide. Amateur astronomers of all ages like to use binoculars to watch the night sky. You can find binoculars in prices ranging from ten dollars to one thousand dollars.
Many astronomers are professionals, but amateur observers have embraced the romance of stargazing also. Binoculars are the perfect accessories for hiking, fishing and hunting.
