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]   Abell 1656, a cluster of over 1000 galaxies in the constellation Coma Berenices. 09 April 2024. John Hughes. More.
[2/12]   The Sun imaged in Hα light. The enlarged insets show the major limb prominence at the 4 o'clock position. The image was captured during a break in the clouds and a lull in the winds of Storm Kathleen! 07 April 2024. Martin Cook. More.
[3/12]   Active region AR3615 soon to disappear over the western limb of the Sun. Imaged in white light with a ZWO Seestar S50 "smart" telescope. 27 March 2024. Paul Whiting, FRAS. More.
[4/12]   Comet 12P/Pons-Brooks imaged with a Dwarf II "smart" telescope. The appearance of the comet has changed as it approaches perihelion, and it shows little evidence of the dark lane recorded eight months previously by another OASI observer. 22 March 2024. Michael Maran. More.
[5/12]   The Sun imaged in white light with a ZWO Seestar S50 "smart" telescope. The solar disk shows granulation, faculae and sunspots. 09 March 2024. Stephen McElvanney. More.
[6/12]   The venue at the Space Invaderz event at Suffolk Aviation Heritage Museum immediately before visitors arrived. The giant astronaut proved to be very popular! Members of OASI provided support by showing visitors the night sky through a variety of telescopes. 24 February 2024. Martin Cook. More.
[7/12]   OASI's presence at the 2024 Norwich Science Festival attracted much attention from visiting members of the poublic. 22 February 2024. Christina Nunn. More.
[8/12]   The IM-1 lunar mission, marked "IM-1" en route to the Moon where it placed 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.
[9/12]   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 minimal post-processing. 11 February 2024. Andy Gibbs. More.
[10/12]   An auroral display seen through cloud from Helligskogen, 142 km south-east of Tromsø, Norway. 20 January 2024. Paul Whiting, FRAS. More.
[11/12]   IC1795 and IC1805, two small star clusters embedded in emission nebulae at a distance of 7500 light years. 19 December 2023 - 15 January 2024. John Hughes. More.
[12/12]   Two views of Jupiter. LHS: Andy Gibbs, 19 December 2023. RHS: Carl Baldwin, 17 December 2023. In both images, the Great Red Spot is visible in the southern hemisphere of the planet. More.
