About this observatory

In Nacton, Suffolk, on the English coast near Ipswich, Orwell Park observatory has been watching the sky since 1874. Built for the Orwell Park estate, it now hosts regular public open evenings run by a local astronomical society.

About Orwell Park observatory

Orwell Park observatory was completed in 1874 as part of the Orwell Park estate in Nacton, Suffolk, England. It was designed in 1872 by George Tomline and built by the instrument makers Troughton & Simms, and at the time of its construction its telescope ranked among the 25 largest in the world.

History

The observatory's first director was the professional astronomer John Isaac Plummer, who took up the post in June 1874. Under his and later observers' work, the observatory published observations of 48 comets, along with studies of Venus, meteors, lunar occultations, zodiacal light, and the 1878 transit of Mercury.

Telescopes and research

The observatory's principal instrument is a 10-inch (258 mm) Tomlin refractor. Its programme of nineteenth-century observational astronomy, covering comets, planetary transits, occultations and meteor work, placed it among the notable private observatories of its era.

Location and getting there

The observatory stands in Nacton, on the Suffolk coast close to Ipswich and the Orwell estuary, in the east of England. Its coastal, low-light setting has long made it a workable site for night-sky observation.

Visiting Orwell Park observatory

The observatory is now cared for by the Orwell Astronomical Society (OASI), which runs regular public open evenings for visitors to look through the historic telescope and learn about the site's history. Check OASI's website for current dates before travelling.
