examples: Do the stars scintillate at all altitudes? Is there any altitude at which it ceases to manifest itself? At Morges the stars in general scintillate at all altitudes, although feebly near the zenith; but on the nights when the scintillation is very faint, it ceases completely at a zenith distance of 45°.
It is generally believed that the planets do not scintillate at all, or scarcely at all. Nevertheless I have often observed a sensible scintillation of Venus and Mars, and in a few rare cases I have also observed a slight scintillation of Jupiter and Saturn. […] I would therefore call the attention of observers who may find themselves under atmospherical conditions of a nature to render the general scintillation very strong, to this point, as they might perhaps be able to ascertain whether Jupiter and Saturn ever sensibly scintillate.
A star, or other point-like source, viewed through the atmosphere can be seen by eye to fluctuate in intensity. An extended object has a brightness distribution that is convolved with the seeing disk. That is, the object's brightness distribution can be thought of as a series of point sources of different brightness, each one 'blurred' to the size of the seeing disk and each seeing disk is scintillating. If the eye could spatially resolve each of these points, it would see brightness fluctuations across a source. However, the resolution of the human eye (≈ 1′) is much poorer than the seeing (≈ 1″). […] The result is that the eye perceives an extended source as steadily shining.
