Observing By Moving The Telescope Manually; Activate The Arrow Keys; Slew Speeds - Bresser Goto-Kit Instruction Manual

Note:
Upon initial switching on,
the hand box prompts
you for country and loca-
tion (Observing Site). You
must manually search for
your country at this point
and then the nearest city;
the entries will be saved
automatically. A subse-
quent change is possible
in the setup menu under
„Location".

Observing by Moving the Telescope Manually

After the telescope is assembled and balanced as described previously, you are
ready to begin manual observations. View easy-to-find terrestrial objects such as
street signs or traffic lights to become accustomed to the functions and operations
of the telescope. For the best results during observations, follow the suggestions
below:
• When you wish to locate an object to observe, first loosen the telescope's R.A.
lock (17, Fig. 1a) and Dec. lock (1, Fig. 1a). The telescope can now turn freely
on its axes. Unlock each axis separately and practice moving your telescope.
Then practice with two unlocked axes at the same time. It is very important to
practice this step to understand how your telescope moves, as the movement
of an equatorial mount is not intuitive.
• Use the aligned viewfinder to sight-in on the object you wish to observe. When the object
is centered in the viewfinder's crosshairs, re-tighten the R.A. and Dec. locks.
• Once centered, an object can be focused by turning one of the knobs of the
focusing mechanism.

Activate the Arrow Keys

The arrow keys of the handbox allow you to slew (move) the telescope up, down,
right, or left. The following procedure describes how to activate the arrow keys:
1. After the power supply is applied in accordance with regulations and the hand box
cable is inserted into the HBX port of the operating panel (Fig. 1b), a copyright
message initially appears on the LED display (1, Fig. 2).
2. After switching on, you will be prompted for the date, time and the summertime
arrangements, in addition to the observing site.
3. The main screen appears in the display upon completion of the entries.
You now can use handbox's Arrow keys to move the telescope to observe.

Slew Speeds

The hand box offers a total of eight slew speeds which are directly proportional to the
sidereal speed. They have been designed so that special functions can be carried out
optionally. Press the number button and adjust the speeds so that the slew speed is
modified; this then appears to the bottom left of the LCD screen of the hand box.
The nine available speeds are:
Number Key 1 =
Number Key 2 = 2x =
Number Key 3 = 8x =
Number Key 4 = 16x =
Number Key 5 = 64x =
Number Key 6 = 128x =
Number Key 7 = 256x =
Number Key 8 = 512x = 120 arc-min/sec or 2°/sec
Number Key 9 = Max. = 120 arc-min/sec or 2°/sec
Speeds 1, 2, or 3: Best used for fine centering of an object in the field of view of a
higher power eyepiece, such as a 12mm or a 9mm eyepiece.
Speeds 4, 5, or 6: Enables centering an object in the field of a low-to-moderate
power eyepiece, such as the standard Super Plössl 26mm.
Speeds 7, 8 or 9: Best suited for the coarse setting of an object. With this, the tel-
escope moves quickly from one place to another in the sky.
