Item description for Observational Astrophysics (Astronomy and Astrophysics Library) by S. Lyle Pierre Lena...
Written specifically for physicists and graduate students, this textbook focuses on fundamental and sometimes practical limitations on the ultimate performance that an astronomical system may reach, rather than presenting particular systems in detail. This second edition has been entirely restructured and almost doubled in size, in order to improve its clarity and to account for the great progress achieved in the last 15 years. It deals with ground-based and space-based astronomy and their respective fields. It presents the new generation of giant ground-based telescopes, with the new methods of optical interferometry and adaptive optics. But it also presents the ambitious concepts behind space missions aimed for the next decades. Avoiding particulars, it covers the whole of the electromagnetic spectrum, and touches upon the "new astronomies" becoming possible with gravitational waves and neutrinos.

takes you to the frontiers Apr 11, 2005
Astronomy is going through exciting times, as new and better instrumentation and methods gives us greater insight into the universe. This book helps explain what some of the advances are. It gives basic material about radiation, photometry and the like. There is an important explanation of how the atmosphere has traditionally limited the resolution of images (at least in the visible spectrum) due to turbulence. Which leads the book into some of the attractions of space-based telescopes.
But the book also goes into how ground based telescopes are overcoming the atmospheric barrier. Using adaptive optics in "smart" telescopes. This lets them cancel out the effects of turbulence, on the time scale of that turbulence. Very impressive. We can push to the instrinsic limits of the optics.
The book takes you to the frontiers of modern astronomy.
