and press ENTER. The display will then ask you to enter first the R.A. and then the declination of the desired object. Save Land Object: The telescope can also be used as a spotting scope on terrestrial objects. Fixed land objects can be stored by saving their altitude and azimuth relative to the - Celestron CGE Pro Mount | CGE Pro Series Manual - Page 26

To compensate for this, the direction of the drive control keys can be - Celestron CGE Pro Mount | CGE Pro Series Manual - Page 28
far as 10 degrees beyond your Meridian. Favor West - If the target object is accessible from both sides of the mount, selecting "Favor West" instructs the telescope to point to the object as if it were on the west side of the meridian.

Up to this point, this manual covered the assembly and basic operation of your telescope. However, to understand your telescope more thoroughly, you need to know a little about the night sky.

Motion of the Stars The daily motion of the Sun across the sky is familiar to even the most casual observer. This daily trek is not the Sun moving as early astronomers thought, but the result of the Earth's rotation. The Earth's rotation also causes the stars to do the same, scribing out a large - Celestron CGE Pro Mount | CGE Pro Series Manual - Page 38
way to polar align a telescope is with a latitude scale. Unlike other methods that require you to find the celestial pole by identifying certain stars near it, this method works off of a known constant to determine how high the polar axis should be pointed.
