Almost every serious amateur astronomer aspires to have his or her own observatory. This book shows how many astronomers have built their own observatories, often employing effective and sometimes ingenious improvisations to reduce the cost. The book gathers together details on a wide variety of small observatories in Europe and the US, accompanied by photographs and construction facts. Interesting anecdotes on the trials and tribulations of the builders are also included, plus helpful tips on design and construction and pitfalls to avoid.
