Your Telescope
Please look for a suitable location for your
telescope before you begin. Use a stable sur-
face e.g. a table.
Mount the Telescope to the Tripod with the
locating screw for the vertical fi ne adjustment
(7). Plug the Ocular (6mm or 20mm) into the
Zenith mirror (2).
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 eye-
pieces 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 eye-
piece, the smaller the magnifi cation! There is
a simple formula for calculating the magnifi ca-
tion:
Focal width of the telescope tube : Focal
width of the eyepiece = magnifi cation
You see: The magnifi cation is also depends
on the focal width of the telescope tube. This
telescope contains a telescope tube with fo-
cal width of 360 mm. From this formula, we
see that if you use an eyepiece with a focal
width of 20 mm, you will get the following
magnifi cation:
360 mm / 20 mm = 18 x magnifi cation
To make things simpler, I've put together
a table with some magnifi cations:
Telescope Focal

focal width eyepiece
360 mm 20 mm
360 mm 6 mm

• Design: achromatic
• Focal width: 360 mm
• Objective Diameter: 50 mm
