Eclipsing Binary Observing Guide
Revised edition of the Eclipsing Binary Observing Guide now available
Eclipsing binaries can be studied with a range of techniques, all the way from simple naked eye observations of some of the brighter systems, through using binoculars or small telescopes, via imaging with DSLR cameras, all the way to sophisticated electronic imaging systems. This handbook provides the observer with a detailed guide to observing these objects. It covers the basic categories of eclipsing binaries, which stars the beginning observer might like to follow, how to interpret the resulting light curve and how to extract the all-important “time of minimum”, corresponding to mid eclipse.
The original Handbook was written by Des Loughney, the VSS Eclipsing Binary Secretary, in 2011. I’m extremely grateful to Des for preparing this revised edition which contains much updated information. Both Des and I are also grateful to Chris Lloyd for revising the list of target stars on the VSS eclipsing binary programme.
The Eclipsing Binary Observing Guide can be downloaded from the VSS website in PDF format for free. It is hoped that we can offer printed copies for sale in the future.
