The outer edge of the chart is the horizon with the compass points marked. The chart is oriented as one is looking south. The constellation outlines in magenta are those of the Zodiac. The magenta line is the ecliptic, the path of the sun. The white line that passes through the east and west compass points is the celestial equator, above the earth's equator. The white lines that cross in the north at the north celestial pole are major right ascension lines and are like meridians on the earth.

All constellations shown have the standard three letter abbreviation. Not all constellations are shown, faint and small ones were deleted for overall clarity. The constellation abbreviations, names and bright star names are found here.

Also on the sky dome are helps to locate other stars and constellations from the Big Dipper, and asterisms.
