Why the sky is constantly changing?

because of the movements of the Earth:
as the Earth rotates on itself, we see the sky scroll as if we were on a ride: the whole sky seems to turn the hours around a point near the pole star (center of the map). This causes the "rises" and "sets" of the stars. In addition, the stroke of the Earth around the Sun shows us a different portion of the sky depending on the time of year.
because of the movements of the celestial bodies themselves:
The Sun, Moon, planets, have a perceptible movement over days (or weeks) to the background of stars. Conversely, stars outside our solar system are so distant that they appear stationary in a human life.

Stelvision sky map: online version vs printed version

  • the online map can be adjusted very easily to a specific place; it indicates the planets (and the Moon)
  • the Stelvision 365 printed map can be taken anywhere, no network or battery problem. With its well readable format (with the associated small lamp) and impeccable impression is a nice object to consult and to offer! It is adjustable for any date of the year with sufficient precision to identify the stars from locations between 40°N and 55°N (including Canada, most of the USA, most of Europe and much of Asia). The planets are shown on special identification cards inside the brochure for a period of 4 years.
...finally, many followers use both versions, which are complementary!
