General Warnings
• Risk of blindness — Never use this device to look directly at the sun or in the direct proximity of the sun.
Doing so may result in a risk of blindness.
• Choking hazard — Children should only use the device under adult supervision. Keep packaging mate-
rial, like plastic bags and rubber bands, out of the reach of children, as these materials pose a choking
hazard.
• Risk of fire — Do not place the device, particularly the lenses, in direct sunlight. The concentration of light
could cause a fire.
• Do not disassemble the device. In the event of a defect, please contact your dealer. The dealer will con-
tact the Service Centre and can send the device in to be repaired, if necessary.
• Do not expose the device to high temperatures.
• The device is intended only for private use. Please heed the privacy of other people. Do not use this
device to look into apartments, for example.
Your telescope consists of these parts:
1 Focus wheel
2 Telescope (Telescope tube)
3 Telescope table
4 Height adjustment wheel
5 Eyepieces (6mm, 20mm)
6 Moon Filter
Please look for a suitable location for your telescope before you begin. Use a stable surface e.g. a table.
Pointing your telescope
With the height adjustment wheel (4) you can point the telescope at any object you want.
Use the height adjustment (4) to slowly move the telescope up and down.
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
width is indicated in millimeters, and is written on each eyepiece. In general, the following is true: The larger
the focal width of an eyepiece, the smaller the magnification! There is a simple formula for calculating the
magnification:
Focal width of the telescope tube : Focal width of the eyepiece = magnification
You see: The magnification is also depends on the focal width of the telescope tube. The telescope has a
focal length of 300 mm
From this formula, we see that if you use an eyepiece with a focal width of 20 mm, you will get the following
magnification:
300 mm / 20 mm = 15 x magnification
