The universe is beautiful and mysterious. Every star light comes from countless years ago. Let's explore the past and future together with children.
A little knowledge about astronomical telescopes:
1. Magnification=objective lens focal length/eyepiece focal length * multiplier. Although the multiple can be increased by replacing the magnification mirror, the larger the multiple is, the better the image is.
2. The larger the objective aperture of the astronomical telescope is, the better. This is very important. The larger the aperture is, the stronger the focusing ability is, and the clearer the imaging is, which can be applied to larger multiples.
3. The astronomical telescope adopts the reflection principle, so the image is inverted. Because there is no positive and negative star sky, it doesn't matter. But when observing ground objects, we can use our 1.5X positive imaging multiplier.
4. For common celestial bodies, Saturn's rings can be seen at a magnification of 30 times,the lunar surface can be seen at 45 times, and the lunar sea on the lunar surface can be clearly seen at 90 times. Jupiter's rings can be seen at a magnification of 300 times.
Description:
1. This is the best gift for children to cultivate their scientific interest, stay away from games and mobile phones, and improve their imagination. It is also suitable for adults.
2. Use scene: animals and plants far from the ground. The moon at night, Jupiter, nebula and so on.
Note: Do not observe the sun directly, or your eyes will be damaged. (You need to use a special Bard film for sun observation)
Product features:
1, 114MM large aperture objective lens, with strong light gathering ability and clear imaging, is suitable for large multiple observation.
2, Enlarge 31MM eyepiece to protect eyes and make imaging wider.
3, 700MM long focal length, the longer the focal length, the greater the magnification.
4, Including three kinds of eyepieces, 20MM, 12.5MM and SR4. With 1.5X and 5X magnification mirror, the maximum magnification is 875X.
Usage method:
Please do not observe the sun directly, or it will hurt your eyes. You need to cooperate with professional Bard film.
1. For the first use, the primary mirror and the stargazing mirror need to be calibrated. The calibration method can refer to the ground objects to ensure that the primary mirror tube and the stargazing mirror are in a straight line.
2. The astronomical telescope adopts the reflection principle, and the image is inverted. Because the sky has no positive and negative sides, it doesn't matter. But when observing ground objects, we can use our 1.5X positive imaging multiplier.
