The PoleMaster is an easy, convenient and fast way to achieve excellent polar alignment.  It has been recognized by astronomy enthusiasts around the world and has become a must-have for anyone using an equatorial mount for visual use or for imaging.  The PoleMaster electronic polar axis alignment device is a patented product of QHYCCD and is protected by Chinese, US patents and International PCT.

As any seasoned astroimager would agree, achieving good polar alignment is not an easy task. You may spend hours under precious dark sky trying to get that perfect polar alignment, but in the end you may not know whether good alignment has in fact been achieved. Even after you have obtained good alignment, a gentle knock on the mount may send the polar alignment off and you may have no other choice but to start from scratch again. With an hour here and an hour there trying to get polar aligned, it soon will be dawn and time to pack up the geari.

The PoleMaster is a great solution to this problem. The PoleMaster is an innovative product pioneered by QHYCCD to relieve the pain of polar alignment. Using PoleMaster and following a few simple, easy-to-follow, steps you can achieve perfect polar alignment in 2-3 minutes, with an accuracy of up to 30 arc seconds.

With Polemaster, You don’t need to rotate the telescope to some uncomfortable position to keep the optical polar axis of the equatorial mount unobstructed.  Also, you don’t need to squat down to look through the polar axis scope.  You don’t need to turn off all the light sources to allow the naked eye to adapt to the darkness and look for the Polaris in the field of view. You also don’t need to enter the date and time and then rotate the equatorial mount to a strange angle, finally you don’t need to adjust the equatorial level. With the PoleMaster you can observe the alignment of the polar axis at any time, as well as continuously monitor the polar axis. When the equatorial mount moves inadvertently, you can also tune it back without having to redo everything.

The PoleMaster’s pixel resolution is approximately 30 arc seconds. The camera’s pixel matrix itself is a good ruler, so the accuracy it measures is much higher than the accuracy of the macroscopic lens. In the best case it can achieve an alignment accuracy of 30 arc seconds.

Wide Field of View: The electronic polar mirror has a large field of view of 11 degrees x 8 degrees, so it is easy to find the Polaris.

Once you have calibrated with a PoleMaster, you only need to perform a single-star sync (one-star calibration).  This greatly facilitates the setup of an equatorial mount.

With a suitable adapter ring, the PoleMaster can be mounted to any equatorial mount. Even single-axis equatorial mounts that have no ability to correct in declination will benefit because with the PoleMaster, after the polar axis is aligned, the amount of drift in the declination direction will be very small, which can further improve the performance of such an equatorial mount.

* The adapter differs for different mounts. The standard package should include a mount adapter (type to be specified when ordering). However, some dealers may sell the PoleMaster without an adapter or sell the adapter seperately.
