How to assemble the telescope
Before you get started with the assembly, you should take some time to decide where you would like to set up your telescope. It is important that you choose a place from which you have an uninhibited view of the sky, where the floor is hard and even, and where you have enough space around you so that you feel comfortable. When you’ve found the ideal spot, you can begin the assembly
Open the locking clips on the tripod legs (16). Then pull the lower parts of the tripod legs (15) downward as far as they will go. Finally, close the locking clips again (Abb. 1). You can change the height of the tripod at a later time by making the tripod legs a bit shorter (again, opening the locking clips, adjusting the legs, closing the clips).
Connect the telescope tube (8) to the tripod head (Abb. 2). Use the Fixation screw for the Telescope tube (12) to firmly connect both parts.
How to insert an eyepiece
Take the lens cap off the eyepiece holder (2). You can now place the amici prism (3) into the eyepiece holder and secure it with the small screw on the connector. Next, set the eyepiece (5) into the opening of the amici prism (3). Here too, there is a screw with which you can screw the eyepiece onto the amici prism.
Note: First, put the eyepiece with the largest focal width (e.g. 20 mm) onto the amici prism. While you’ll get the least amount of magnification, it will be easier for you to view things.
Barlow Lens
Optional: The Barlow lens can be mounted between the amici prism and the eyepiece to further triple the magnification.
Installing the battery
- Open the battery compartment cover clockwise with a screwdriver.
- Insert a CR2032 button cell battery, paying attention to the correct polarity.
- Hold the battery compartment cover in the appropriate position and hand-tighten it anti-clockwise.
Using your telescope
To move the scope up, down and side to side, grip the telescope and steadily move the tube until your target comes into view in the eyepiece. It is important to remember that the rotation of the Earth means objects will move out of your eyepiece fairly quickly. Once you have found and focused on your desired target, you will have to track the object as it journeys across the night sky. For a closer look at an object, you can insert the 4 mm eyepiece. The magnification will increase from 20x to 100x.
Which eyepiece is right?
It is important that you always choose an eyepiece (5) 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:
Formula for calculating magnification:
Examples:
Focal length (Telescope)
| | Focal length (Eyepiece)| | Magnification| | Barlow Lens 3x
---|---|---|---|---|---|---
400 mm| ÷| 20 mm| =| 20X| x3|
= 60X
400 mm
| ÷| 8 mm| =| 50X| x3| = 150X
400 mm| ÷| 4 mm| =| 100X| x3|
= 300X
Focus wheel
Look through the telescope eyepiece (5) and hone in on a far away object that you can see well (for instance, a church tower). Focus in on the object with the focus knob (1).
Technical data:
- Design: achromatic
- Focal length: 400 mm
- Objective diameter: 70 mm
Notes on cleaning
- Clean the eyepieces and lenses only with a soft, lint-free cloth, like a microfibre cloth. To avoid scratching the lenses, use only gentle pressure with the cleaning cloth.
- To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass-cleaning solution, and wipe the lenses gently.
- Protect the device from dust and moisture. After use, particularly in high humidity, let the device acclimatise for a short period of time, so that the residual moisture can dissipate before storing.

Telescope ABC’s What do the following terms mean?
Focal length:
Everything that magnifies an object via an optic (lens) has a certain focal length. The focal length is the length of the path the light travels from the surface of the lens to its focal point. The focal point is also referred to as the focus. In focus, the image is clear. In the case of a telescope, the focal length of the telescope tube and the eyepieces are combined.
Lens:
The lens turns the light that falls on it around in such a way so that the light gives a clear image in the focal point after it has traveled a certain distance (focal length).
Amici Prism (diagonal) (3):
| A
roof prism that redirects the light beam at a right angle. With a horizontal
telescope tube, this device deflects the light upwards so that you can
comfortably observe by looking downwards into the eyepiece. The image appears
upright and laterally correct through an amici prism.
---|---
Barlow Lens (4):
| The Barlow lens can be used to increase the focal width of a telescope.
---|---
Eyepiece (5):
| An eyepiece
is a system made for your eye and comprised of one or more lenses. In an
eyepiece, the clear image that is generated in the focal point of a lens is
captured and magnified still more. There is a simple formula for calculating
the magnification: Focal length of the telescope tube / Focal length of the
eyepiece = Magnification In a telescope, the magnification depends on both the
focal length of the telescope tube and the focal length of the eyepiece. From
this formula, we see that if you use an eyepiece with a focal length of 20 mm
and a telescope tube with a focal length of 400 mm, you will get the following
magnification: 400 mm / 20 mm = 20 times magnification
---|---
Magnification:
The magnification corresponds to the difference between observation with the naked eye and observation through a magnifying device like a telescope. If a telescope configuration has a magnification of 30x, then an object viewed through the telescope will appear 30 times larger than it would with the naked eye. See also ‘Eyepiece’.
