Astronomical seeing is that blurring and twinkling phenomena of various astronomical objects such as stars, which is naturally caused by the turbulent ...

Astronomical Seeing Part 1.

'Seeing' is a simple measure for how steady the Earth's atmosphere appears to be. In particular, we use it when we study the Moon and planets.
