This is a used Polemaster in what appears to be excellent condition in its original metal case. It includes the USB cable. Please note that this DOES NOT include an adapter for use with your mount; you will have to purchase that separately from another vendor.
QHY PoleMaster Electronic Polar Scope
The QHY PoleMaster allows you to obtain a high precision polar alignment (up to 30 arcseconds) in about two minutes!
The PoleMaster polarscope 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 polar scope, 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.
Please Note: The Polemaster polar scope has an 11 x 8 field of view so you will need at least 4 degrees of unobstructed sky around Polaris for it to function properly.
*The PoleMaster cannot be used without the proper adapter.

Mac Users Take Note: While QHY offers a beta version of the Polemaster polar scope software for those using Apple computers, it is strongly recommended not to use it as customers have experienced issues and are not able to get the camera to work correctly, if at all. As a result, it is strongly recommended to use a Windows-based operating system.
