Why is the East on the left and West on the right
side of this diagram?
Think of the view as though you were looking
up into a hemispherical sky above your head. Print out a
copy, hold it above your head and the East, West orientation is
correct.

Sky Background Colours
Between sunrise and sunset the sky is coloured light
grey. At twilight times it's dark grey and during the night it's
black.
The Ecliptic
The orbits of most planets in the solar system lie in the same plane which is
known as the ecliptic. Click the 'Show Ecliptic' to see where it crosses
the sky.
+ and - I Hour Buttons
Click these buttons to advance or retard the display time by one hour. Click
them rapidly and watch how the stars and planets rise in the east, move accross the
sky; and set in the west. See
how the sun and planets track close to the ecliptic. Look for conjunctions as
planets move close together, and as they pass through constellations.
Bright and Dim Stars and Planets
The bright stars ahown are the main navigational stars and have magnitudes
of less than 3. Dim stars are included to complete constallations and help with
their identification. SkyViews show only the 4 navigational planets ie. Venus,
Mars, Jupiter and Saturn.
The Moon
Note that Sky Views do not show the Moon's phase.
