This page shows the starry sky for 50° north latitude at 0 hours sidereal time. It is approximately 0 hours sidereal time at 0 hours local time at the end of September, at 18 hours local time at the end of December, at 12 hours local time at the end of March, and at 6 hours local time at the end of June.

The black disk indicates the sky, in stereographical projection. The circle at the outer edge of the disk is the horizon. The middle of the disk is the zenith. North is up, east to the left, south at the bottom, and west to the right. The white dots are stars of magnitude 3.5 and brighter. The larger the dot, the brighter the star.

The green lines are lines of constant height and azimuth in the horizontal coordinate system, and the green numbers show that azimuth (the upper number of each pair) and height (the lower number).

Four constellations are indicated in blue. At 0 hours sidereal time, Orion is just rising in the east, the Great Bear (Ursa Major) is low in the north, Cassiopeia is almost overhead, and the Swan (Cygnus) is in the west.
