This polar sight device is used to better polar align WLT's tracker, but with minor changes can be adapted to other trackers.
This device is using a laser to point to a polar star (example Polaris) and together with a polar alignment app (example Polar Clock app by Zsolt Nagy) can lead to better results on mount polar alignment.
Because the laser beam colimation is important, the laser pointer needs to have the sighting mechanism for adjusting the beam in order to calibrate the device before use.
The calibration process should be easy and could be performed on daylight, see the instructions on the PDF file.
