The focus knob (8, fig. 2):
It causes a fine internal movement of the main mirror in the
telescope in order to achieve a precisely focused image. The MCX can focus on objects
between a minimum distance of about 50m and infinity. Turn the focus knob clockwise
to focus on distant objects; turn the focus knob counterclockwise to focus on closer
objects.
Operation of the tilting mirror (Fig. 20):
An optical plane mirror is built into the MCX. If
the tilting mirror moves as shown in Fig. 20 is in the "UP" position, the light is deflected
at a 90° angle to the eyepiece. If, on the other hand, the tilting mirror is in the "DOWN"
position, this is shown in Fig. 21, the light passes straight through the telescope into the
photo port (15, fig.
2). This allows you to use the telescope with an optional T-adapter
for telephoto or astrophotography. More detailed information can be found in chapter
"Optional accessories" on page 36.
NOTE!
The tilting mirror is in the "UP" position when the knobs are vertically aligned, shown in
Fig.
20. It is in the "DOWN" position when the knobs are aligned horizontally (parallel to the
telescope tube), as shown in Fig. 21.
The interface field
The interface field (Fig. 22) on the MCX includes a connector for the standard handheld
computer. In addition, there is a connector for the external power supply and an auxiliary
socket (socket for accessories, see "Handheld computers" on page 22).
ON/OFF (1, fig. 22):
When the ON/OFF switch is moved to the ON position, the red
indicator lamp for the power supply lights up (5, fig. 22). The handheld computer and the
telescopic drive are now supplied with power.
AUX (2, fig. 22):
This accessory port is used to connect future accessories.
NOTE!
The AUX port (2, fig. 22) at the interface is foreseen for future developments, but not
currently active. Unfortunately there are no accessories available at the moment. We may
inform you about new developments for this product on our website at www.bresser.de/

WATCH OUT!
Use of unauthorized products may damage the telescope electronics and void your
warranty.
HBX (3, fig. 22):
The HBX connector is used to connect the handheld computer using the
supplied spiral cable.
12V (4, fig. 22):
The 12V connector is intended for use with an external power supply.
For more information, refer to chapter "Optional Accessories" on page 36. As soon as you
use this alternative power supply, the internal batteries are disconnected from the circuit.
NOTE!
If you do not use the instrument for a long time, always remove the batteries. This
prevents damage from leaking battery acid.
