Automatic tilt compensation
When the “
” symbol is shown on the display, the vertical angles is automatically compensated for small tilt
errors using the tilt sensor.
Elimination of parallax
Parallax is the relative displacement of the target image with respect to the reticle when the observer’s head is
moved slightly up and down or to the sides while looking through the telescope. Parallax will introduce reading
errors and must be eliminated before observations are taken. Parallax can be removed by refocusing the reticle.
Power-saving automatic cut-off
To save power, power to the KTS-442UT is automatically cut off if it is not operated for 30 minutes. It is possible
to turn the automatic power cut-off function ON or OFF function. Refer to “23.1 Changing Instrument
parameters”.
Leveling by the tilt angle display
It is possible to display the state of tilt of the instrument graphically or numerically and level the instrument. The
tilt angle correction range is ±3.5′. (As below, press SFT then press • ) If the displayed angle value exceeds ±3.5′,
the instrument needs to be leveled manually.
