DOWNLOAD EBOOK →A study is presented of one year of systematic zenith observations made with similar photometers at two observing stations:Haleakala (latitude N 20.7 degrees) and Fritz Peak (latitude N 39.9 degrees).It is shown that, for an effec * tive wavelength of 5300 A, there is a change of intensity with sidereal time (and therefore right ascension) due to three components:(1) integrated starlight, (2) zodiacal light, and (3) airglow continuum. Quantitative separation of the components is made.A critical comparison is made with some earlier investigations with particular reference to the problem of the galactic light.(Author).

DOWNLOAD EBOOK →Excerpt from Absolute Photometry of the Light of the Night Sky: The Zenith Intensity of Haleakala (Latitude N 20. 7°) And at Fritz Peak (Latitude N 39. 9°) The earth-bound Observer not only has to attempt the resolution of the three components but also must contend with the effects of the extinction and scattering of the lower atmosphere. The problem of making the extinction and scattering corrections becomes progressively more difficult as the horizon is approached but, fortunately, zenith observations are not seriously affected.

DOWNLOAD EBOOK →In the vast expanse of the universe, where the night sky reveals countless stars, planets, and galaxies, the pursuit of knowledge knows no bounds. Among the many tools at the disposal of astronomers and astrophysicists, photometry stands as a beacon of precision and insight. This book, "Photometry: Science, Sensitivity, and Its Connection to Astronomy," is your guided journey into the fascinating world of measuring and interpreting light in the cosmos. As you gaze upon the night sky, you might wonder: How do astronomers decipher the secrets held within the twinkling stars and distant galaxies? The answer lies in photometry, a powerful technique that allows scientists to quantify and analyze the luminous emissions of celestial objects. From determining the properties of stars and planets to unraveling the mysteries of the cosmos itself, photometry serves as the bedrock of astronomical research. In this book, we embark on an exploration of the science of photometry, delving deep into its principles, techniques, and applications. Whether you are an aspiring astronomer, a seasoned researcher, or simply a curious soul with a passion for the night sky, this book will illuminate the path to understanding the luminous tapestry of our universe.
