Welcome

OASI is a society for people interested in astronomy. We are based at Orwell Park Observatory and Newbourne Village Hall, both situated near Ipswich, Suffolk. Members enjoy a wide range of interests in astronomy and include armchair astronomers, casual observers, and dedicated amateurs with specialist skills in visual and photographic observing, constructing telescopes, public education in astronomy and the history of astronomy.

[1/12]   The venue at the Space Invaderz event at Suffolk Aviation Heritage Museum immediately before visitors arrived. The giant astronaut suit provided the perfect background for selfies! Members of OASI provided support by showing visitors the night sky through a variety of telescopes. 24 February 2024. Martin Cook.
[2/12]   The Sun imaged in Hα light. The enlarged insets show a limb prominence and detail around the large sunspot. 23 February 2024. Martin Cook. More.
[3/12]   The IM-1 lunar mission, marked "IM-1" en route to the Moon where, if all goes to plan, it will place a lander on the surface, becoming the first commercial organisation to do so. The image is centred on IM-1, so stars appear as trails. 18 February 2024. Nigel Evans. More.
[4/12]   The Orion Nebula (M42) is the first light object for OASI's newly-purchased ZWO SeeStar S50 "smart" imaging telescope. A stack of five minute exposures with no post processing. 11 February 2024. Andy Gibbs. More.
