 Automatic elimination of parallax
Parallax here is the difference of the positions between the telescope reticle and the top corner
of the triangle displayed on the screen. There exists a parallax because the built-in camera and
the telescope are not on the same axis.
When a distance is not measured or the instrument/telescope is moved after a measurement, a
triangle is displayed on the screen, which indicates a parallax exists. Once a distance is
measured, DS detects the parallax and eliminates it automatically then telescope reticle is
displayed on the screen.
