Celestron CPC 9.25 User Manual page 7

each month looks towards the northern sky and the other the south. The telescope has a database
of about 50 stars it will accept as alignment stars.
Pick an appropriate star chart and find two stars highlighted (underlined) on the chart that you can
identify in the sky. Having a mobile device with a planetarium app, such as SkySafari, beside you will
make this task easier and more reliable.
Until you complete the two-star alignment procedure, the telescope has no idea where it is pointing
in the sky or where objects are located. The star alignment procedure gives the telescope the
accurate location of two initial stars. From this, it can then determine the location of all the
thousands of objects in its database. So, the initial star alignment procedure is critical to a successful
night under the stars.
