Adaptive Optics for Astronomical Telescopes
This book by one of the leaders in adaptive optics covers the fundamental theory and then describes in detail how this technology can be applied to large ground-based telescopes to compensate for the effects of atmospheric turbulence. It includes information on basic adaptive optics components and technology, and has chapters devoted to atmospheric turbulence, optical image structure, laser beacons, and overall system design. The chapter on system design is particularly detailed and includes performance estimation and optimization. Combining a clear discussion of physical principles with numerous real-world examples, this book will be a valuable resource for all graduate students and researchers in astronomy and optics.

The McQueary Clan
John McQueary, Sr. settled in Reddies River, Wilkes County, North Carolina in about 1779. He had two known sons, William and John, Jr. William (1760-1832) married Nancy Ann Shepherd (b. 1770) and they had twelve children. John, Jr. (1765-ca. 1840) married Nancy Shepherd (b. 1765) and they had eight children. Descendants and relatives lived mainly in North Carolina, Kentucky, Indiana and Oklahoma.
Astronomical and Astrophysical Objectives of Sub-Milliarcsecond Optical Astrometry
Astrometry is on the threshold of great changes due to the fact that this decade, alone, is witnessing an improvement of stellar positions equivalent to the total improvement of the previous two centuries. The Hipparcos Satellite has concluded its observations, and the catalog is in preparation. Preliminary results assure that the Hipparcos catalog will provide positions, parallaxes and annual proper motions for over 100,000 stars with accuracies of 1.5 milliarcseconds. In addition, the Tycho catalog will provide positions of about 30 milliarcseconds accuracy for over 1 million stars, and annual proper motions with 3 milliarcsecond accuracy will subsequently be ob tained by means of first ep...
