Discussion made during the span of half a century. Since all this material has resulted in an error of 0″.25 for the height of Mösting A, I believe that we cannot expect much more for other points measured only a few times on photographs taken only recently.

Manifest

The Use of the 48-inch Schmidt Telescope for Selenodetic Observationsalomar Schmidt as a moon-star camera. The Schmidt is rarely in use when the Moon is above the horizon and good supplementary use could be made of the instrument if it should prove adaptable for lunar work.

Photographic Techniques for the Determination of the Moon’s Constants of Rotationtter approach. In this no reference is made to the limb and the weakness of the classical method, that is, the vagueness of the center of figure, is avoided. Instead the selenodetic coordinates are referred to a visible point on the lunar surface as origin.

Note on a Photometric Determination of the Moon’s Form from Eclipse Observations is located close to this face, rotating with the prism and oriented normally to the limbs of the Sun and the Moon. A field lens, following the slit, forms an image of the objective on the photocathode of a photomultiplier, and the photocurrent is recorded between the second and third contacts of the eclipse.

Investigating the Moon’s Motion by Laser Rangingata processing techniques. The possibility of extending radar astronomy to optical wavelengths, where angular resolution characteristic of optical astronomical telescopes might be expected, attracted attention almost as soon as the invention of the laser light source suggested such a possibility. This extension is now becoming a practical reality.
