1.
Mount the telescope on the tripod and set it up in a location where the Moon is visible. Check
that the telescope is stable.
2.
Adjust the tripod height for easy observations.
3.
Turn the telescope roughly toward the Moon, then use the Viewfinder to fine tune the pointing.
4.
Focus on the Moon by rotating the draw tube.
5.
After you find the right focus, try observing different parts of the Moon.
The Moon, which does not shine by itself, is visible only because of the sunlight reflecting from
its surface.
You can see this clearly when you observe the terminator between the sunlit and shadowed
areas. You can also see rough terrain (craters, etc.).
Large and obvious, the Moon is an excellent target for beginning observers. The Moon's shape
and moonrise times change every day.
First, use the Eyepiece (large) and observe at low magnification.
After you master targeting and focusing, try observing other objects.
Besides this manual, you can find more information
for setup and usage of the telescope on the internet.
This manual is also available in downloadable format.
Observe the Moon!

The NAOJ Telescope kit was developed by the National Astronomical Observatory of Japan (NAOJ) "One
Family, One Telescope" project. This project aims to deliver a safe and affordable telescope for astronomy
education to classrooms in Japan and around the world. This project was realized with the generous support
of 272 crowdfunding supporters including Mr. Norio Sasanuma. We believe this project will realize our
hopes of fostering children's interest in the Universe and inspire humanity to greater achievements through
astronomy.
Notes
Let's Begin the Observation of Heavenly Bodies
Above all things, you should pay attention to the safety of yourself and your surroundings.
●
NEVER observe the Sun
with this telescope. Extremely strong sunlight can cause serious
damage to your eyes, possibly inducing permanent blindness. The excessive heat from
observing the Sun can also damage the telescope and degrade its performance.
●
Choose an observation site with a level, solid floor. Mount the telescope on a stable tripod.
Pay attention to conditions that may interfere with safe observations, such as strong winds
that could knock over the telescope.
●
Choose an open space and keep your surrounding clear so as not to collide with other people
or obstacles.
●
During observations on dark evenings, stay aware of your own safety. Also pay attention so
as not to cause any trouble for other people.
