LAND AND SKY TELESCOPE
#5F5F7B2
CAUTION:
Never attempt to observe the sun with this telescope! Especially keep in mind while the telescope is used by children!
Observing the sun – even for a very short time as this may cause blindness!
Packing material (plastic bags, etc.) must be kept out of reach of children!
RISK to your child!

9 Tripod legs
Your telescope
Please look for a suitable location for your telescope
before you begin. Use a stable surface e.g. a table.
Mount the telescope to the tripod with the locating
screw for the vertical adjustment (7). Insert the eye
piece into the diagonal mirror (12.5mm or 20mm).
Azimuthal mounting
Azimuthal mounting just means that you can move your
telescope up and down, left and right, without having to
adjust the tripod. Use the locating screw for the vertical
fi ne adjustment (7) and the locating screw for the
vertical axis (8) to locate and lock the position of an
object. (to focus an object)
Which eyepiece is right?
First of all, it is important that you always choose an
eyepiece with the highest focal width for the beginning
of your observation. Afterwards, you can gradually
move to eyepieces with smaller focal widths. The focal
length is indicated in millimetres (mm) and is written
on each eyepiece. In general, the following is true: The
larger the focal width of an eyepiece, the smaller the
magnifi cation! There is a simple formula for calculating
the magnifi cation:
Focal length of the telescope tube: Focal length of the
eyepiece = magnifi cation
The magnifi cation also depends on the focal
length of the telescope tube. This telescope
contains a telescope tube with focal length of
360mm. From this formula, shows that if you
use an eyepiece with a focal width of 20mm, you
will get the following magnifi cation:
360mm / 20mm = 18x magnifi cation
To make things simpler, here is a chart
showing the magnifi cations.
Technical data:
• Design: Achromatic
• Focal length: 360mm
• Objective diameter: 50mm
Possible objects for observation:
We have compiled and explained a number of
very interesting celestial bodies and star
clusters for you but we suggest that you start
practicing during the day focusing on terrestrial
objects such as birds and or trees at varying
distances from you. On the accompanying
images at the end of the instruction manual, you
can see how objects will appear in good viewing
conditions through your telescope at varying
powers (see pictoral examples below).
Terrestrial views
Please note the example picture of Mount
Rushmore. Start with the 20mm eyepiece and
focus until clear. After mastering the focus with
the 20mm change the 12.5mm eyepiece and
practice focusing and scanning until images
become clear in the eyepiece. We have included
some additional examples that are possible with
your telescope such as a bird and a green on a
golf course. DO NOT POINT YOUR TELESCOPE
DIRECTLY AT THE SUN OR BLINDNESS IS
POSSIBLE.

Advice:
Remove dust protection
cap and sun-shield from
the objective opening.
Adjust focus using focus
ring
Wait for temperature to
balance out
Never observe through a
glass surface
Adjust fi nder
Problem:
No picture
Blurred picture
No focus possible
Bad picture
Viewing object visible
in the fi nder, but not
through the telescope
DISPOSAL
Dispose of the packaging materials
properly, according to their type (paper,
cardboard, etc).
Contact your local waste disposal service
or environmental authority for information
on the proper disposal.
Please take the current legal regulations
into account when disposing of your
device. You can get more information
on the proper disposal from your local
waste disposal service or environmental
authority.
