QHY Polemaster

Telescope House are pleased to supply the QHY Polemaster - a revolution in the sphere of Polar alignment of Equatorial telescope mounts.

The Polemaster is an alignment camera that with an appropriate adapter (available additionally) will fit a huge range of commercially available mounts - just pick your adapter, and fit the Polemaster simply to the polar boresight or polar arm/bracket of your mount.

The Polemaster is attached via USB to a nearby PC or Mac, on which QHY's Polemaster app is installed.  The Polemaster app analyses the image feed from the Polemaster camera and gives precise instructions on how to adjust your mount's elevation and azimuth adjusters in order to acheive a percise polar alignment.  PoleMaster makes use of a super sensitive wide field imaging camera along the axis of RA to monitor the polar region in real time (so not only it can detect Polaris but also the dimmer stars surrounding). From the positions of these stars PoleMaster can determine the position of the true pole and compare that to the mechanical axis of RA rotation. Polar alignment is now a simple matter of moving the two centres of rotation so they overlap.The whole process should take 2-3 minutes and should easily be able to acheive 30 arc second accuracy - all without having to bend down and fight with a polar alignment scope!

QHY are so confident of the accuracy of alignment that the Polemaster can acheive, that they stated that single star alignment should give as accurate results as three star alignment as far as Goto setups are concerned - yet more time saved in your setup routine.

In comparison with other polar alignment techniques, PoleMaster has the following advantage:

1. Speed and convenience: With PoleMaster you do not need to move the telescope to specific place just so to unblock the polar scope. You do not need to kneel or contort your body to look through the polar scope. You do not need to fully dark adapt just to see the pole star. You do not need to level your mount. You do not need to worry about the entering the date and time in your handset and figure out where to rotate the mount to coincide with the current pole star position.

2. Accuracy: With a high precision camera, one can achieve accuracy not achievable with naked eye. As the imaging camera in PoleMaster has a resolution of 30 arc second, the best polar alignment that can be achieved by PoleMaster is also in the order of 30 arc seconds.

3. Wide angle view of the polar region: A wide field of view of 11x8 degree makes it super easy to locate the pole star

4. Easy to install: PoleMaster can be easily installed onto any equatorial mount through mount-specific adapters, even on mount without polar scope.

5. Real time polar alignment checking / adjustment: By using PoleMaster you can monitor your polar alignment in real time. In the event that polar alignment is lost, it is now a simple matter to bring it back without having to start from scratch.

6. Three star alignment no longer needed: Once you are polar aligned, you will only need to perform one star alignment - a real time saver.

7. Perfect companion to single axis mounts: When used with single (RA-only) axis mount, good polar alignment will minimise drift in the DEC axis therefore maximising the performance of your mount.
