This is also easy to detect by you and me, the ordinary hunter who does not hold a degree in the physical properties of light. "Sneak" a peek at the outer corners of the view in the glass while holding the glass still (do not pan). Is edge image sharp or fuzzy? Edge sharpness is nice because it brings the entire field of view into a "flat-screen" view, rather than just the centremost section. High quality binoculars show high optical resolution over the entire picture, not just the centre, although the central portion remains most important.
Astronomical Society of Victoria president Perry Vlahos says anyone interested in starting out in astronomy should not buy a telescope.He says first school yourself: read, join a club or take a course.A pair of binoculars will suffice for those starting out.If you're under the age of 40 invest in a 7x50 pair of binoculars, or if you're over 40 a 10x50.
The term binocular covers a whole range of optics, binoculars, spotting scopes, night vision goggles, and so on. So before you even think of buying a binocular you need to find out what you need and what you are going to use it for. Binoculars are used by people in operas, while hunting, in war, for bird watching, and in astronomy. For astronomy and bird watching you will need high powered binoculars while for other uses you could even consider compact binoculars which weigh little.
Our Astronomical Terrestrial Binoculars are perfect to use instead of a spotting scope. These binoculars offer field of view equal to spotting scopes, but cause less eye fatigue because you are able to use both eyes. We recommend you use a rest or tripod for steady viewing. Each is drilled to accept a tripod adapter. You get great viewing power from these 20 x 80 power binoculars, with a field of vision at 1,000 yards of 157 feet. A tripod adapter also is available.
