Astronomical Seeing

In the Annual Report of the Smithsonian Institution for 1902 Prof. Langley has published an important note on “Good Seeing,” in which he describes some experiments undertaken with the view of improving the definition of telescopic images, so far as it depends on the conditions of the air in the vicinity of the instrument. Up to now the belief has prevailed among astronomers that in order to obtain good definitions the air inside the telescope-tubes should be kept as much as possible not only at a uniform temperature but also in a state of perfect tranquillity. Langley, however, shows that this view is not quite correct, and that maintaining constant and uniform temperature inside the tube, while preventing circulation between the air inside and outside the instrument, is not sufficient to produce satisfactory telescopic images. Particularly, this method does not diminish the troublesome boiling which in solar observations proves so often to be a source of grave inconvenience to the observer. But he shows that if the air inside and near the telescope-tube is agitated by stirring, the definition becomes at once markedly better. The improvement has in all cases been so decided that the reality of this beneficial effect of stirring cannot well be doubted.

Astronomical Seeing

‘Seeing’ affects the light-curve of a stellar occultation by the Moon in two ways: the diffraction pattern on the ground is smeared out by atmospheric turbulence, and the pattern also suffers random displacements. These effects are analogous to the familiar image blur and image motion, respectively. However, there is a major difference between ordinary astronomical seeing and the effect on the lunar diffraction pattern: the former is the seeing looking up at the sky from the bottom of the atmosphere, but the latter corresponds to the seeing looking down through the atmosphere at the surface of the Earth.This downward-looking seeing is of concern to people engaged in aerial photography and satellite reconnaissance, and has been studied theoretically from this point of view. It also enters into the theory of stellar scintillation, because the seeing blurs out the scintillation shadow pattern just as it blurs out the occultation diffraction pattern.
