The Skalnaté Pleso Atlas of the Heavens (Atlas Coeli Skalnaté Pleso 1950.0) is a set of 16 celestial charts covering the entire sky. It is named after the Skalnaté Pleso Observatory in Slovakia where it was produced. The first versions were published by the Czechoslovak Astronomical Society in 1948; later that year, Sky Publishing ...
A ground track from Heavens-Above. An observer in Sicily can see the International Space Station when it enters the circle at 9:26 pm. A bright object appears in the northwest, crosses the sky to a point almost overhead, and disappears, in the span of three minutes.
Visualization of a celestial sphere. In astronomy and navigation, the celestial sphere is an abstract sphere that has an arbitrarily large radius and is concentric to Earth.All objects in the sky can be conceived as being projected upon the inner surface of the celestial sphere, which may be centered on Earth or the observer.

The following table lists the common coordinate systems in use by the astronomical community. The fundamental plane divides the celestial sphere into two equal hemispheres and defines the baseline for the latitudinal coordinates, similar to the equator in the geographic coordinate system. The poles are located at ±90° from the fundamental plane.
Bečvář is particularly important for his star charts: he led the compilation of the Atlas Coeli Skalnate Pleso (1951), published by Sky Publishing Corporation as the Skalnate Pleso Atlas of the Heavens, which was the state-of-the-art atlas of its kind until Wil Tirion's "Sky Atlas 2000.0" in 1981.
