Welcome To OASI,

The Orwell Astronomical Society (Ipswich)

 

Welcome

Welcome to OASI. We are a society for anyone who has an interest in astronomy, telescopes, space travel and related matters. Members of OASI span a wide range of interests and abilities, from the interested layman to the advanced amateur. Current membership of OASI numbers around 100, most members living in the areas of Ipswich, south-east Suffolk and north-east Essex.

We are based at Orwell Park Observatory in the village of Nacton, near Ipswich, Suffolk, UK. The Observatory contains our telescopes, our library of astronomy magazines, books and videos, and a club room. The facilities of the Observatory are open to members of OASI.

OASI was founded in 1967 and is a UK registered charity, no 271313.

Observing

We encourage observing at the Observatory at our weekly Club Evenings and at other times, using telescopes, binoculars and the naked eye.

Telescopes at Orwell Park Observatory available for use by members of OASI include the 26cm f/15 Tomline Refractor, a 48cm Dobsonian reflector constructed by members of OASI  and several smaller, modern instruments.

We organise occasional field trips to observe meteor showers, grazing lunar occultations and other astronomical phenomena.

Astronomy Workshops

During each winter season we hold informal astronomical workshops on a range of topics. The workshops are led by experienced presenters, and vary in style from an interactive, guided, discussion to a traditional lecture. Previous topics have covered an eclectic range including telescopes, observing projects, creating a back garden observatory, history of astronomy, cosmology, and many other topics!

Telescope Making

Several members of OASI are keen amateur telescope makers. They have constructed a 48cm, f4.5 Dobsonian telescope (known as the OASI Millennium Telescope) and several smaller instruments for use by members of the Society.

Over the years, individual members of OASI have also built their own instruments, of varying levels of sophistication, including traditional reflecting telescopes and a Schmidt camera.

History of Astronomy

We have undertaken extensive research into the history of astronomy in the East Anglian region and more widely in the UK. A particular focus of interest has been John Isaac Plummer (1845-1925), the first and only professional astronomer to be based at Orwell Park.

Can you provide any new information on the founding and early years of Orwell Park Observatory - e.g. photographs, press reports? If so, please contact us via the email address to the right.

Social Events

Our Christmas Meal and Summer BBQ are firmly established in the Society's calendar. We undertake occasional excursions to astronomical conventions, places of astronomical interest and neighbouring astronomy societies. We also occasionally arrange visits to events of a non-astronomical nature.

Forthcoming events.
