A: The telescope is an optical instrument to collect light through the telescope can see how far the object and the observer, observe the environment and the observed object and the telescope itself. (If weather is nice, this can be seen 1500 meters above it) 2, a multiple telescope to see more clearly whether the greater? A: observe objects through a telescope, the greater the magnification is not clear, clarity and magnification, brightness, contrast, coating, light transmittance and many other factors. Under sunny weather conditions, can be seen on the ground within 100 meters coin size, within 500 meters can see the license plate, within 1500 meters can see billboards of text. 3, such as the telescope above "8X42" mean? Answer: "×" in front of multiple, followed by objective lens diameter. Such as "8X42" represents the magnification is 8, caliber 42mm telescope. "×" on behalf of magnification. 4, telescope multiples mean? A: indicates the degree of the scene to be closer to the telescope, for example, observed the scene through the 1000 meters at a magnification of 10 times the telescope effect, to not use the telescope directly at the 100 meters with the naked eye to observe the effect of the scene is the same . 5, night vision binoculars can it? A: The telescope is pure optical instruments, all black environment can not be viewed. Field of view for an observation environment particularly broad, there is a certain light, such as street lamps, moonlight, the light is dim but also the naked eye can be observed, this time using the telescope can further see objects, such telescopes known as "night vision" or "twilight" telescope. 6, why dizzy? Usually there are several reasons: 1) At most, the right eye diopter wheel does not adjust well, resulting in burnt imaging mode 2) does not regulate the distance of the exit pupil, the eye is too close to the eyepiece or too far away from the eyepiece. 3) all of a sudden can not adapt to the initial use of the telescope's magnification, plus moving the telescope too frequently observed, hand jitter
