From the reviews: [The] writing style is lucid and eminently friendly, and conveys a virtually contagious enthusiasm for the subject. If, after browsing through this book, you haven't felt the urge to sweep the skies for some of the magnificent star clusters detailed in the text, then you aren't at all interested in viewing the skies. I thoroughly recommend this book. --Peter Grego, in Popular Astronomy, April-June 2006 "Mark Allison is clearly an enthusiast and keen amateur observer of the Deep Sky, and in Star clusters and how to observe them ... . His style is friendly and welcoming to the newcomer to the field. ... The observing aspect of the book is more successful than the astrophysical which has many interesting things to say ... . for the newcomer to star clusters looking for a relatively inexpensive alternative, it may serve." (Nick Hewitt, Journal of the British Astronomical Association, Vol. 116 (4), 2006)
