IMPORTANT INFORMATION

A Word to Parents!

Dear Parents,

With this telescope, your child will be able to

explore the stars in the night sky, or study

natural objects all around us right here on

Earth with the help of the image reversal lens.

To be sure that this optical instrument is

handled correctly, it is essential to pay careful

attention to the instructions and tips provided

in this manual. Please stand by your child’s side

when he or she is learning the relevant skills,

and be ready to offer help when it is needed. In

particular, please note the adjacent safety

information and discuss these points with your

child.

To view the night sky, your child may

sometimes need to work at a time or in a place

requiring you to accompany him or her or at

least to help plan evening outings.

Safety Information

WARNING! Never look directly into the sun

— whether with your naked eye, or with the

telescope or its viewfinder! You could blind

yourself!

Never inadvertently leave the telescope and

its viewfinder in the sun — it could start a

fire!

Keep the packaging and instructions as they

contain important information.

When observing the stars outside, appropriate

tools and equipment are advisable (depending

on the weather and season, this could mean

warm clothing, a Thermos with some hot cocoa,

a red-light flashlight (see page 16), this

instruction manual, and maybe a separately-

purchased star wheel or star map app). Please

help your child with these things.

We wish you and your child lots of fun with the

telescope!

Assembling Your

Telescope

In this chapter, you will learn about all the parts that make up

your telescope and how to assemble them. The stand holds the

telescope for you and helps you keep it pointed at the exact part of

the sky you want to look at. The telescope itself is the long tube

with a glass lens at the front. The rear, narrower end, which is the

end into which you look, is where you will insert various other

glass lenses and other accessories.

NOTE! This applies to both assembly and

subsequent use of the telescope: Tighten all the

screws carefully and only by hand (not using

tools!). Only tighten them as much as they need to

be tightened, not as much as you can tighten them.

Assembling the

telescope

YOU WILL NEED

› Stand

› Three attachment screws

› Shelf with three wingnuts

› Telescope

› Two star-knob tighteners

› Eyepiece

HERE’S HOW:

1. Extend the three legs of the stand to their full

length. Insert the three attachment screws

into the threads in the center of the legs. The

legs should not collapse when you set up the

stand with its legs spread apart.

2. Screw the shelf to the stand’s attachment

bars with its rimmed side oriented upward. To

do that, first unscrew the three wingnuts

from the shelf and then screw them back in

through the holes in the stand’s attachment

bars. Keep screwing until the shelf stops

jiggling.

3. Insert the shiny height adjustment rod, which

is mounted on the side of the telescope, into

the opening in the telescope cradle.

BEFORE YOU START

4. Attach the telescope securely to its cradle by

screwing in the two star-knob tighteners

equally on both sides. The telescope should

then swivel without much force, but it also

shouldn’t be so loose that it moves on its

own.

5. Now, gently tighten the height adjustment

screw.

6. Slide an eyepiece into the eyepiece extension

until it hits the stop and secure it in place

with at least one of the eyepiece extension’s

knurled screws. It is best to start with the

eyepiece with the largest millimeter readings.

TIP!

All of your telescope’s

optical elements have covers

to protect them from dust. If

you remove the cover only

while you are using the

telescope for your

observations and then place

it back on afterwards, the

glass lens will stay clean

longer. Try to avoid touching

the sensitive glass surfaces

with your fingers.

Assembling Your Telescope

Mounting and

adjusting the

viewfinder

YOU WILL NEED

› Assembled telescope

› Viewfinder

HERE’S HOW:

1. The viewfinder must have its larger opening

(the objective) pointing away from the

viewer.

2. Loosen the two knurled screws at the end of

the telescope, insert them into the two holes

in the viewfinder bracket, and tighten them

again. The holes in the bracket are elongated.

Make sure that the viewfinder sits parallel to

the telescope.

3. Outside during the day, point the telescope at

a target on the horizon at least 500 meters

away (such as a tower, tree, or building).

TIP!

You should adjust the

viewfinder during the

daytime.

BEFORE YOU START

4. Focus the telescope by turning the eyepiece

extension and move the observation target

right into the middle of the field of view.

5. Look through the viewfinder and focus it by

turning its eyepiece.

TIP!

When looking through the viewfinder or

the telescope, you will notice that

everything is turned upside-down. It’s

supposed to look that way (see page 10).

For observation targets on the ground,

your telescope comes equipped with an

image reversal lens (see page 21), which

will display images in their usual

orientation.

Assembling Your Telescope

View through the telescope (top); view through the

viewfinder: misaligned (center) and aligned (bottom).

6. When you look through the viewfinder, you

will notice that the observation target is not

in the center of its field of view, but shifted

off to the side instead. Use the three knurled

screws to adjust the viewfinder until the

center of its field of view matches that of the

telescope. To do this, keep loosening one or

two of the screws while you tighten the

other(s). You will probably have to repeat this

several times. Keep looking into the

viewfinder to verify that the observation

target is moving toward the center of the

field of view.

7. If adjustment of the three knurled screws is

not enough, you will have to loosen the two

knurled screws again on the viewfinder

bracket and correct the viewfinder’s

orientation before returning to the viewfinder

alignment instructions described in step 6.

8. After orienting the viewfinder, all three

knurled screws should be gently tightened

again so that the viewfinder doesn’t

inadvertently shift in its bracket. Finally,

check one last time to make sure that the

viewfinder and the telescope show the same

observation target in the center of their fields

of view.
