Star clear

The title of this article is ambiguous. For the “Sternklar” design by the Stuttgart garden architect Siegloch, see Ebertpark

The meteorological designation of a night sky with no or only light cloud cover is star- clear , so that the starry sky becomes visible.

The astronomers differentiate between further criteria:

• Transparency of the atmosphere (usually on a scale from 1 to 5)
• Limiting magnitude (the faintest freely visible stars)
• Air turbulence (turbulence in the troposphere) and its effects as scintillation (twinkling of the stars) or as seeing (movement of the star points in the telescope)
• Disruption from moonlight and urban light pollution .
