Pro Astronomical Telescope 114mm Aperture 875X Zoom HD High Resolution

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)
