Now in its 9th edition, this introduction to the night sky for beginners has been in print since 1987 and has earned some enthusiastic reviews. The Monthly Sky Guide (MSG) was originally the working title; we never found anything better.

In many ways MSG continues the tradition of 19th-century guidebooks such as R. A. Proctor’s Half Hours with the Stars. Each month opens with an all-sky chart for mid-evening by Wil Tirion, which is followed by descriptions of the main objects on show and detailed charts of particular constellations of interest. The book is intended for northern-hemisphere users only.

Information on the visibility of the naked-eye planets for a five-year period is included in each edition; eclipses were added in the fourth edition (along with any transits that may occur). This time-dependent information introduces a degree of obsolescence into the book, although the bulk of the text refers to objects visible each year and so does not date. Full-colour printing was introduced with the 6th edition in 2003; previous editions had been printed in two colours only. The maps have been subtly improved with each edition since.

The eighth edition, published in autumn 2009, saw the first major change in content since the book first appeared. New sections were added on observing the Moon and the planets, including four pages of realistic Moon maps based on US Geological Survey originals. This expanded the length of the book from 64 to 72 pages, although the price remained the same.

The planetary and eclipse information in MSG9, published at the start of 2013, covers 2013–2017. The book is printed from layouts supplied by me in Quark XPress. The same printing is sold in the UK, US, and Canada. Danish and Greek translations are currently in print, although with different edition numbers. A French-language edition is published under the title l’Observation du ciel; this was expanded to 112 pages for the 3rd edition (2011). There is also a Polish edition, Miesińôczny przewodnik po niebie, first published in 2014.
