Antoniadi (Michel)

The Antoniadi (Michel) scale is a system used by astronomers to rate the quality of the view through a telescope, especially when observing planets and the Moon. It ranges from I (perfect seeing, very clear and steady) to V (poor seeing, very blurry and unstable). This scale helps astronomers assess how good the viewing conditions are, influenced by factors like atmospheric turbulence and brightness. By assigning a level from this scale, observers can communicate the clarity of their observations and compare viewing conditions over time or across different locations.
