QHY CCD PoleMaster - High Precision, Easy to Use Electric Polar Scope
Good polar alignment can be performed relatively quickly using special finder scopes with polar reference reticles, but to get the precise polar alignment that will make your mount perform at its best for high quality astrophotography and science measurements, often requires time-consuming drift alignment. The QHYCCD PoleMaster reduces the time to achieve precise polar alignment in a few minutes with an accuracy of 30 arc seconds.
The PoleMaster requires an adapter to allow the unit to fit in your polar axis.
