This book is about observing dramatic and often bizarre cosmic events. Observation of gamma ray bursts, cataclysmic variable star outbursts, distant supernovae, and even active galactic nuclei might be thought to be far beyond the range of amateur observers but this is not the case. Recent technical developments in CCD equipment, powerful PCs, new observing and processing techniques, and professional satellite monitoring systems have opened a range of high-value niche areas of scientific astronomy to amateurs. Cataclysmic Cosmic Events and How to Observe them explains what these events are, what we know of their physics, and how amateur astronomers can observe them.The a#39;Single Stara#39; photometry option simply gives you a result on a single star by adding up its light contribution and deducting the background contribution. ... ( Figure 7.6) The great thing about this AIP tool is that you can see the aperture and inner/ outer annulus rings on the screen surrounding the stars ... The first star you click on is the variable star (V), and the second star is the comparison star ( C1).
