An Observational Search for Cosmic Light Open
A total of 28 500 observations of the zenith sky made at three mid-latitude stations is analysed for the purpose of extracting the diffuse light from the totality of extra-galactic light sources. It is not possible to obtain a value for ab…

Surface Photometry of Celestial Sources from a Space Vehicle: Introduction and Observational Procedures Open
Diffuse celestial sources of relatively low surface brightness such as the Milky Way, zodiacal light, and gegenschein (or contre lumière ) can be studied most reliably from above the earth's atmosphere with equipment flown in artificial sa…

A comparison of surface brightness measurements from OAO-2 and OSO-6 Open
A comparison of surface brightness measurements of the night sky from the OAO-2 and OSO-6 satellites with ground observations shows good agreement between the space experiments but a systematic error in the zero point of the ground observa…
