Locating the Celestial Pole

Page 14 highlights

Locating the Celestial Pole In the northern Hemisphere, find the North Star Polaris by facing North. To get basic bearings at an observing location, take note of where the Sun rises (East) and sets (West) each day. After the site is dark, face North by pointing your left shoulder toward where the Sun set. To precisely point at the pole, find the North Star (Polaris) by using the Big Dipper as a guide (See figure below). In the southern Hemisphere, you align the mount to the southern celestial pole. To do this it is necessary to reference star patterns since the southern celestial pole has no nearby bright stars. The closest bright star to the south celestial pole is Sigma Octanis, which is about one degree away. Using Sigma Octanis and other bright stars will help you locate the pole.

Locating the Celestial Pole
In the northern Hemisphere, find the North Star
Polaris by facing North. To get basic bearings
at an observing location, take note of where the
Sun rises (East) and sets (West) each day. After
the site is dark, face North by pointing your left
shoulder toward where the Sun set. To precise-
ly point at the pole, find the North Star (Polaris)
by using the Big Dipper as a guide (See figure
below).
In the southern Hemisphere, you align the
mount to the southern celestial pole.
To do this
it is necessary to reference star patterns since
the southern celestial pole has no nearby bright
stars. The closest bright star to the south celes-
tial pole is Sigma Octanis, which is about one
degree away. Using Sigma Octanis and other
bright stars will help you locate the pole.
