Enhance interest in learning, use astronomical telescopes to intuitively learn astronomical knowledge, broaden your horizons, increase knowledge, and enhance your interest in learning
Increase the interaction between parents and children, entertaining and entertaining, and improve their hands-on ability, responsiveness and creativity

About function:
This is a round island where you can see the moon. Tripod height: 38CM.
About configuration:
The focal length is 300 mm, the aperture is 70mm, and two eyepieces: H6 (for daytime viewing) and H20 (for viewing the moon at night), and a 3 x Ballov lens.
Regarding multiples:
Equipped with eyepieces: H6mm, H20mm, the multiples are: 300/6=50 times, 300/20=15 times. If you choose a 3 times Ballov mirror, the multiplier is 50X3=150 times, 15X3=45 times;
Calculation formula:
Objective lens focal length / eyepiece focal length * several times Ballov's multiple = maximum magnification
Objective lens focal length/eyepiece focal length = magnification
Installation sequence:
Support the tripod first. Then install the lens barrel. After the lens barrel is fixed, install a star finder (used to initially find the target object) on the lens barrel, and then install the eyepiece (choose 1 from 2 eyepieces). After finding the big target, adjust it with different eyepieces. Note: The first time you use it, you must be patient and patient! The possibility of astronomical damage is very, very small, not to mention that every telescope has been strictly inspected before we release it.
● Of course, the multiple is not the only one, it mainly depends on the comprehensive factors such as aperture and focal length.
● When using a 3 x Ballov mirror, install the Ballov mirror first, and then install the eyepiece.
(To install the Ballov lens, you need to remove the cover on the device where the eyepiece is installed.)
Note: 2 eyepieces (H6mm, H20mm) can only choose one to install at the same time
