Gerry A. Good – författare

Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That''s where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good''s book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.

L’osservazione delle stelle variabili è uno dei principali contributi che gli astronomi dilettanti possono offrire alla scienza e questo libro fornisce tutte le informazioni necessarie per dedicarvisi con profitto.Nella prima parte vengono presentate in dettaglio le diverse classi di variabili, con esempi, curve di luce e descrizioni fisiche. La seconda sezione copre invece tutti gli aspetti pratici dell’osservazione: dalla preparazione e la pianificazione, alle tecniche osservative, fino alla gestione e all’elaborazione dei dati.Questo è un volume indispensabile e completo per chi voglia impegnarsi nell’osservazione delle stelle variabili, adatto per tutti gli astrofili, dai principianti fino a quelli che hanno già maturato un discreto livello d’esperienza e di abilità.
