Tárgy: Re: Spotting Scope
Sziasztok!
Az alábbi oldalon a következőket találtam arról, hogyan is
válasszunk
"spotting scope-ot". Ez talán segit eldönteni, hogy mi is ez az
eszköz.

How to Choose a Spotting Scope
A spotting scope is a compact telescope designed primarily for
terrestrial
observing and is used in applications which require magnifications
beyond
the range of a typical binocular. Compared to telescopes designed
primarily
for astronomy, a terrestrial telescope usually is designed with a
shorter
focal length for lower magnifications and wider fields of view and it
has
some type of erecting prism system to deliver a correctly oriented
image to
the viewer.

Spotting scopes are ideally suited for such activities as long distance
birdwatching and nature study (shorebirds and raptors, for example),
telephotography, scenic observing, long distance microscopy, beginning
astronomy, hunting, target shooting and surveillance. It´s important to
determine your primary use for the instrument as the optical design
will
directly affect its ability to perform under various conditions and its
flexibility for different applications.
