Product Description

Astronomical telescope student
Product Introduction:
Calculation formula:
Objective focal length / eyepiece focal length * several times Barov multiple = maximum magnification
Objective focal length / eyepiece focal length = magnification
Installation order:
Set up the tripod first. Then install the lens barrel. After the lens barrel is fixed, install the finder lens on the lens barrel (used to initially find the target object), and then install the eyepiece (choose 1 of 2 eyepieces). After finding the big target, then adjust it with different eyepieces. Note: For the first time, you must be patient and patient! The possibility of astronomical failure is very, very small, not to mention that every telescope has been strictly checked before we send it out.
WARNING!
Never look directly at the sun through a telescope or finder unless you have the proper solar filter. Failure to do so can result in eye damage that is permanent and irreversible.
Children should be used under the supervision of an adult and should be used according to the steps.
What to Look For in the Sky
There is a whole universe of objects to be seen in the night sky so where does one start?
Well lets examine the most visible objects first.
The Moon
The moon is the easiest target to find at night. When it is in all directions, when the whole face is illuminated, it will bathe the night with silver light and wash away all objects except the brightest objects in the sky. The best time to watch the moon is actually not the full moon, but any time until the first quarter, when the face looks half bright. The terminator on the moon, the dividing line between darkness and light, shows the best features, such as craters and mountains.
The Planets
The Planets are our solar system. These objects range in size from moon size rocky objects to giant balloons that can hold 1000 earths. Finding these planets requires some information about when they are visible. Astronomical magazines, such as sky news or sky and telescope, will provide you with the positions of the planets every month. Most people who look up at night may have seen some planets, but they are not aware of them. When a planet is far from the horizon, it does not twinkle like a star. They are recognized by the eye as small spheres, while stars are infinitely small light spots. The most visible planets are Venus, Mars, Jupiter, Saturn, Uranus and Neptune. Mercury is an object to look for, but it is usually below the horizon and often a challenge. Pluto is too small for most telescopes under 10 inches, so don't worry about finding it now.
