The QHY PoleMaster allows you to obtain a high precision polar alignment (up to 30 arcseconds) in about two minutes!
The PoleMaster uses a sensitive camera to take a picture of sky around Polaris. Because the camera is much more sensitive than your eyes, it can see the faint stars that surround the North Star, providing a more exact location of true north. The PoleMaster uses this image to calculate the NCP, and that is the first step in achieving a precise polar alignment.
The QHY PoleMaster is installed on the front of the RA axis with the proper mount adapter (sold separately) and is designed to detect the rotation center of the right ascension axis. This information, along with the location of the North Celestial Pole, is marked on the screen of the PoleMaster, and it is then a simple matter of adjusting the mount until the two marks overlap.
Once you have done this simple, quick alignment, you can monitor your polar alignment throughout the night. If you accidentally move the mount, it is easy to re-align by simply overlapping the two marks.
