Book Reviews of The Observer's Sky Atlas: With 50 Star Charts Covering the Entire Sky

Book Review: A very handy field book for the non-novice
Summary: 4 Stars

After examining the contents I saw that the added size was put to good advantage. The same basic charts are there from the first edition, but just a little larger in scale. And now there is quite a bit more information packed on the opposing pages that describe the objects to be viewed. Binary or multiple stars with significant relative motions are plotted so that you can see how the relationship will change over the next 20 years. A visual plot is given of the position angle of these stars rather than just a number. Little thermometers indicate the relative temperatures of each component to give an idea of the color difference to be expected. For regular variable stars a small waveform is often included that describes the period and change in brightness of the star. A set of symbols is now used to describe the ease of visibility of objects and objects with low surface brightness are noted using the same symbols. Several other columns have been added that are to assist in finding an object on the adjacent chart and to identify its magnitude. Although I did not find these particularly useful, others may.

At the beginning of the book there is a chart that I do not remember from the first edition that describes how natural and man-made light pollution affects the view of objects and shows how many objects can be seen under what conditions. All together the books positive changes balance the negative ones nicely. It will still be my first choice at the telescope. One negative that might exist for users new to the sky is that now there may be too much information on each page. I do not think that will be a problem for most. Thanks for the new edition!
