PoleMaster - a high precision, easy to use electric polar scope. Achieving a high precision polar alignment is not easy. You may spend tens of minutes, if not hours, to get a good polar alignment. After you get everything ready and begin taking exposures, you bump the mount, and have to restart from the beginning. 

The most straight forward way for polar alignment is just to find the true north point and match its position with the rotation center of your R.A. axis. The PoleMasterTM electronic polar scope employs this idea. This device can be installed on front of the R.A. axis. It use a highly sensitivity camera to capture the image of northern sky. The sensitivity is much higher than the naked eye, so it can see not only the Polaris but also those faint stars nearby. Based on the locations of these stars, it can calculate the true position of the North Pole. 

With some sophisticated methods the PoleMaster can also detect the rotation center of the R.A. axis. It will mark the two points on the computer screen, one is the R.A. rotation center, the other is the virtual polar point. Adjust the mount and let them overlap then the pole is well aligned. 

Please select the correct mount from pull-down menu when ordering.
