in the sky over Moscow

The proposed map creates a starry sky image corresponding to the current time and given coordinates of the terrain.
For Moscow, the coordinates of Exhibition of Achievements of the National Economy - 55.83 ° N and 37.62 ° E were chosen.
When using the map, it should be taken into account that the local time in Moscow differs from the zonal Moscow time, counted from the Greenwich meridian, on average 30 minutes. Figure 1 shows: the winter starry sky and the region of stars that never enter the latitude of Moscow..
Inside this region are six constellations that do not extend beyond its boundaries: Ursa Minor; Draco; Camelopardalis; Cassiopeia; Cepheus and Lacerta - they are called circumpolar stars.
No matter how the position of the constellations on the star map does not change (Fig.2), non-passing constellations always remain on it:
