PoleMaster by QHYCCD - a high precision, easy to use electric polar scope. By using a simple design and small camera and specialized brackets, the Polemaster allows your mount to "see" where it is pointed. This wide field polar scope features smart and easy to use software that calculates your position quickly and accurately.

QHYCCD PoleMaster - a high precision, easy to use electric polar scope

Accomplishing a high accurate polar alignment is not a simple deed. You might invest a considerable amount of time and energy in it yet you do not know if it is really well aligned and you never know how good it is aligned. After you get everything prepared and start taking exposures and then touched the mount unintentionally, it is back to square one to perform polar alignment, three star alignment, goto the target and begin taking exposure again. You may waste another hour to do that and to your dismay you realize the sun is rising...

The QHYCCD PoleMaster is a wide field polar scope that can tackle these issues remarkably. It gives you an immediate and straightforward approach to align with the pole. Within two minutes you could acquire high polar alignment precision up to 30 arcsec.


Technology Overview

How to get the pole well aligned. The most straightforward thought is just to locate the true north point and coordinate its position with the rotation center of the RA axis. QHYCCD's PoleMaster incorporates this idea. This device can be installed on front of the RA axis, It utilizes a very sensitive camera to catch the picture of northern sky. The sensitivity is much higher than the unaided eye, so it can see the polaris as well as some weak star close-by. In view of the areas of these stars, it can figure the position of the true position of north pole. With some sophisticated methods the PoleMaster can also detect the rotation center of the RA axis. It will mark the two point on the screen, one is the RA rotation center, another is the virtual polar point. You can adjust the mount and let them overlap then the pole is well aligned.

To analyze the old innovation of the polar arrangement. The upsides of QHYCCD PoleMaster are:


Fast, Easy and Comfortable

You don't have to turn the telescope to a few positions to permit the wide field polar scope to see the sky. You do not need to lie down or squat to adjust the mount. You do not need to switch off all the lights and observe through the QHY PoleMaster electronic polar scope carefully to find the pole star. You do not need to input the date and time, rotate the mount to a strange angle. you do not need to adjust the  horizontal balance anymore.


High precision.

The pixel resolution of this PoleMaster is approx.. 30arcsec/pixel. The picture sensor itself can be viewed as a good ruler. A great deal more accurate and sensitive than the unaided eyes. In best condition, it can get pole precision down to 30 arcsec.


Wide field. Easy to find the north star.

The QHYCCD PoleMaster has a 15*10 degree field of view. You can find the north star easily with this wide field polar scope.


Can be installed on any mount.

PoleMaster can installed on any mount with a suitable connector. Even your mount has no polar scope, that doesn’t matter.


Pole Monitor/align at any time.

With the QHYCCD PoleMaster wide field polar scope you can monitor the polar alignment at any time. When the mount is moved by accident, you can adjust it back directly without redo the whole process.


No Need 3-Star Calibration Anymore.

After done aligenment by PoleMaster, your mount does not need 3-star calibration anymore. Just using the 1-star calibration or single star sync you can get your mount ready for GOTO.


Support both north and south hemisphere
