A Roll-off Roof Observatory in New Boston, New Hampshire, USA,This is the third observatory we have built since we purchased our first telescope in 1983.

We decided to build the observatory ourselves due to money considerations — we had a new mortgage and had just ordered an Astrophysics 7 in (178 mm) f/9 refractor.

,Patrick Moore’s Observatory in Selsey, England,As I am essentially an observer of the Moon and planets, it may be said that my observatory is of the “old-fashioned” type, and this is no doubt true enough!
