Assembly Procedure 2 [Eyepieces]
This kit contains the parts for two eyepieces.
Please check the combination of lenses and Housing parts.
Place the Tripod Connection NutⓁ into the hexagon shaped pit.
1. First, determine the sides
of the lenses. Each lens
has a at side and a convex
(bulged) side. If you place a
lens in the wrong orientation,
the telescope will not work
correctly.
2. Disassemble the combined Eyepiece HousingsⒹ
and Ⓔ, and mount the two lenses for each in the
slots engraved inside of them. Refer to the gure
carefully.
In EyepieceⒹ (large), the convex side of both lenses
faces toward the wide opening of the Housing. In
EyepieceⒺ (small), the two lenses' convex sides
should face inside toward each other.
3. Fit the two sides of the eyepiece housings together.
Take care not to let the lenses shift out of position.
4. Insert two screws (short)Ⓝ in the holes on each
eyepiece marked in the picture and tighten to hold
the parts of the Eyepieces rmly together.
5. Attach the Eye PadⒻ to the tip of each eyepiece.
1. Fit the two sides of the Draw TubeⒸ together.
2. Set the assembled Draw TubeⒸ in the Body TubeⒶ.
Let the grip of the Draw Tube stick out, and t the screw threads on the outside of the Draw
Tube into the threads on the inside of the Body Tube.
1. Fit the left side of the Body TubeⒶ over the right half.
Take care not to let the lens or the nut shift out of position.
2. Attach the Lock RingⒷ to the bottom of the Body TubeⒶ to join the parts.
3. Insert four screws (long)Ⓜ in the holes marked in the picture and tighten to hold the parts of

How to use this Telescope 2 [Viewnder]
A telescope with a high magnication has a narrow FOV so that pointing it at the target is not
easy. A Viewnder can help you aim. The Viewnder of this
telescope consists of a "Front Sight" (a protrusion on the tip of
the hood) and a "Rear Sight" (a sighting ring at the back of the
body tube).
How to use this Telescope 3 [Eyepieces]
The magnication of the telescope can be
changed by exchanging eyepieces†. The
image condition changes according to the
magnication.
Selecting the appropriate eyepiece (magnication) is important for good observations.
●When rst pointing the telescope at an object, use the Eyepiece (large) with the lower
magnication because its wider FOV makes it easier to nd the object.
●To observe bright, compact objects in detail, the Eyepiece (small) with the higher
magnication is more e󱐯ective.
●In contrast, to observe faint, extended objects, the Eyepiece (large) is better because of its
wider FOV and brighter image.
The detail specications of the Eyepieces are written at the end of this document.
1. Look into the Rear Sight ring from behind.
2. Watch the target object through the center of the Rear Sight ring, and align the Front Sight
marker in-line between the Rear Sight and the target. If the luminous sticker on the Front Sight
loses its glow, illuminate it with a ashlight for a while to recharge it. You should try not to look
at the ashlight because it can dazzle your eyes and interfere with the observations.
3. After aligning the telescope properly with the Viewnder, the target will appear in the FOV of
the telescope.
How to use this Telescope 4 [Shooting Photos]
This kit includes a guide ring for a small camera to help you shoot photos through the telescope.
1. Attach the Guide RingⓆ to your smartphone camera or web camera with adhesive tape.
2. Fit the Guide RingⓆ into the depression of the Eyepiece to align them. Then shoot photos.
●When your hand trembles while holding the smartphone, it
disturbs the shooting. Try to damp the trembling by resting
your elbows on a stable place or folding your arms tightly
to your sides.
●Functions to lock the focus and/or brightness (AE/AF lock),
can be useful if available on your camera.
※Depending on the object image conditions, you may need to adjust the
camera settings (sensitivity, exposure, and so on.)
※To master the use of the Viewnder practice on obvious objects, such as distant buildings.

Assembly Procedure 5 [Tripod]
How to use this Telescope 1 [Focus]
It is necessary to use a tripod for stable observations.
You need to focus the telescope to observe objects.
Focus by adjusting the position of the Eyepiece based on the distance to the target.
1. Use a general-purpose tripod for a still/video
camera†. Tighten the tripod mount screw into the
Tripod Connection NutⓁ (Ⓑ) on the bottom of
the telescope.
2. Set the tripod on a level, solid oor. Spread the
tripod legs fully apart and adjust the height to a height suitable for observation.
† standard 1/4" mount screw size
1. Attach Eyepiece (large) (lower magnication) to the Telescope and point it at a distant location.
An image seen correctly through an astronomical telescope is inverted (rotated 180 degrees).
Do not worry about this.
2. Point the telescope at a distant object, such
as a sign board or a chimney, then rotate
the grip of the Draw Tube until you get a
sharp image. Be careful not to force the
Draw Tube.
A telescope cannot focus on nearby
objects. Please observe objects at least 5
meters or so away.
3. If you cannot get the right focus, even by
adjusting the Draw Tube, please check if
all the lenses are assembled in the correct
positions and orientations.
If you use this telescope outside during the daytime, be careful NOT to point the
telescope near the Sun.
A properly focused image An out of focus image
† The magnication value is calculated as the primary lens focal length divided by the eyepiece focal length.

14 15
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 Viewnder to ne tune the pointing.
4. Focus on the Moon by rotating the draw tube.
5. After you nd the right focus, try observing di󱐯erent parts of the Moon.
The Moon, which does not shine by itself, is visible only because of the sunlight reecting 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 magnication.
After you master targeting and focusing, try observing other objects.
Besides this manual, you can nd more information
for setup and usage of the telescope on the internet.
This manual is also available in downloadable format.
Observe the Moon!

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 oor. 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.
