Version 02
Fix the tripod to the tripod head with the help of the wing screw, washers and wing nuts (Fig. 1). Attach the
middle span to the tripod spans with the small screws (Fig. 2). The golden circle on the middle span must
be pointing upwards. Finally, screw the accessories caddy (14) onto the middle span.
Next, screw the vertical fine adjustment to the protruding silver metal supports on the telescope tube. It is
best if you let someone help you. Then you need to attach the telescope tube to the tripod. To do so, use
the spiral screw with the washers to screw the tube to the tripod head (Fig. 5). Attach the locking screw for
the vertical fine adjustment to the tripod head yoke (Fig. 6).
Version 01+02
Depending on the telescope model you have, screw your viewfinder or LED viewfinder to the holder (Version
1, Fig. 3) or insert it directly (Version 2, Fig. 3). Then affix the viewfinder with screws. Check carefully which
step is right for your viewfinder.
Take the lens cap off the eyepiece (6). You can now place the zenith mirror (16) into the eyepiece holder
and secure it with the small screw on the connector (Fig. 4). Next, set the eyepiece (15) into the opening
of the zenith mirror (16) (Fig. 4). Here too, there is a screw with which you can screw the eyepiece onto the
zenith mirror.
Note: First, put the eyepiece with the largest focal width (e.g. 20 mm) onto the zenith mirror. While you'll get
the least amount of magnification, it will be easier for you to view things.
Which eyepiece is right?
It is important that you always choose an eyepiece (15) 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:
Focal length (Telescope) ÷ Focal length (Eyepiece) = Magnification
Examples:
600 mm
600 mm
600 mm
Use of the moon filter
If the image of the moon is too bright for you, you can screw the green moon filter (17) into the bottom of
the thread of the eyepiece (15). Then you can set the eyepiece normally into the zenith mirror (16). The
image that you see by looking through the eyepiece is now greenish. The moon appears less bright, so
observation is more pleasant.
