Slew Speeds
LX80 has nine slew speeds that are directly
proportional to the sidereal rate (the rate at
which stars appear to drift across the sky)
and have been calculated to accomplish
specifi c functions. Pressing a Number key
changes the slew speed, which is shown for
about two seconds on AudioStar’s display.
To change the speed, press the
appropriate key shown below.
Nine available speeds are:
Number Key 1 = Guide (0.25 arc-min/sec
or 0.004°/sec)
Number Key 2 = 2x = 2x sidereal (0.5 arc-min/sec
or 0.008°/sec)
Number Key 3 = 8x = 8x sidereal (2 arc-min/sec or
0.033°/sec)
Number Key 4 = 16x = 16x sidereal (4 arc-min/sec
or 0.067°/sec)
Number Key 5 = 64x = 64x sidereal (16 arc-min
sec or 0.27°/sec)
Number Key 6 = 128x = 30arc-min/sec or 0.5°/sec
Number Key 7 = 1.5° = 90arc-min/sec or 1.5°/sec
Number Key 8 = 3° = 180arc-min/sec or 3°/sec
Number Key 9 = Max = 270arc-min/sec or 4.5°/sec
Speeds 1, 2 or 3: Best used for fi ne centering of an
object in the fi eld 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
fi eld of a low-to-moderate power eyepiece, such as the
standard 26mm.
Speeds 7 or 8: Best used for rough centering of an
object in the viewfi nder.
Speed 9: Moves the telescope quickly from one point
in the sky to another.
