Welcome

OASI is a society for anyone interested in astronomy. We're based at Orwell Park Observatory in the village of Nacton, near Ipswich, UK, and most of our members live in the counties of Suffolk and Essex. Our current membership is over 120.

Members enjoy a wide range of interests in astronomy. They include those with a casual interest, through occasional observers, to dedicated amateurs with specialist skills in visual and photographic observing, constructing telescopes, public education in astronomy and the history of astronomy. We encourage and support the astronomical activities of our members. Our activities include:

• regular observing sessions at Orwell Park Observatory and Newbourne Village Hall;
• occasional field trips to observe grazing lunar occultations and meteor showers;
• winter season astronomy workshops hosted by members of OASI;
• winter season lectures, most by external speakers;
• activities jointly with neighbouring astronomical societies;
• social events.

Orwell Park Observatory is equipped with several astronomical telescopes including the 260 mm Tomline Refractor (an instrument of major historic interest dating from 1874), portable reflectors of aperture 200 - 250 mm and refractors of smaller aperture. The Society encourages use of the instruments and provides training where necessary. The observatory also houses a club meeting room and a library of astronomical resources.

We are a UK registered charity (no. 271313) founded in 1967.
