Overview
The Dunedin Astronomical Society Incorporated is an amateur astronomy organisation based in Dunedin, New Zealand. Its principal facility is the Beverly-Begg Observatory in the Belleknowes area, from which the society conducts public viewing sessions, astronomical instruction, member observation activities, and practical work related to telescope construction and use. The organisation is affiliated with the Royal Astronomical Society of New Zealand and the Otago Institute. The society was founded on 27 September 1910 in a meeting held in the Chemistry Room of the University of Otago. Originally established as the Otago Astronomical Society, it brought together people interested in observational astronomy and astronomical equipment. R. Gilkison was elected president at the founding meeting, with Rev. P. W. Fairclough and J. M. Garrow as vice-presidents; Thompson Lamb became honorary secretary and W. S. Wilson honorary treasurer. In 1911 the society affiliated with the Otago Institute and became its astronomical section for a period. Its early membership was substantial, with 254 members reported in 1912. The organisation’s early development was shaped by the search for a permanent observatory. Around 1915 it operated a temporary Telescope House on Tanna Hill in the grounds of the University of Otago, but the university later required the land for construction. A proposed site near the Dunedin Botanic Gardens was not developed immediately because of delays associated with the First World War. In 1920 the society selected land at Belleknowes, and the observatory there was completed in 1922. The facility subsequently became known as the Beverly-Begg Observatory. The society has combined public education with member-focused observing and instrument making. Its stated objectives include promoting astronomy and telescope making, maintaining the observatory, offering regular public viewing nights, teaching astronomy to privately arranged groups, holding lectures and practical demonstrations, and providing members with access to society-owned astronomical equipment. Membership is open to anyone with an interest in astronomy rather than being restricted to professional astronomers. Institutional and facility development continued throughout the twentieth and early twenty-first centuries. In 1948 the Telescope Makers’ Club sought access to the society’s facilities and subsequently joined with it. During the 1960s an annex was added to the observatory, creating more suitable space for meetings, talks, and telescope construction. The society became an incorporated society in 2000 and was registered as a charitable society by the New Zealand Charities Commission in 2009. In 2002 it obtained access to a farm cottage near Middlemarch, which members use as a darker-sky observing location away from Dunedin’s urban environment. DAS generally meets twice each month through most of the year, excluding January. The first monthly meeting normally centres on a lecture from a member or guest speaker, while the second is dedicated to practical astronomy, including observing when weather permits and discussions of equipment and observing methods. During winter, when daylight-saving conditions do not apply, the Beverly-Begg Observatory is opened to the public on Sunday evenings. Educational and private groups can also arrange observatory access. The society supports observing and small-scale scientific programmes. Members use the Middlemarch cottage for dark-sky work, and piers were installed there in 2013 for Sky-Watcher EQ6 telescope mounts. A magnetometer and data logger at the cottage provide measurements for solar-wind research conducted by Dr. Yuki Obana of Osaka Electro-Communication University. Members also participate in occultation observing with the observatory’s C14 telescope, a Watec astronomical video camera, and an IOTA-VTI video-timing system. A SBIG ST8300M camera has been used for astrometry and photometry. In 2015 society members recorded a Pluto occultation on 29 June, shortly before NASA’s New Horizons spacecraft flyby of Pluto. DAS marked its centenary in 2010 with lectures, historical activities, a Royal Astronomical Society of New Zealand conference hosted at the Otago Museum, and a public meeting held in the same university room where the society had been founded a century earlier. Its continuing role is that of a volunteer-based astronomical society connecting public outreach, amateur observation, technical skills, heritage, and participation in selected scientific observations.
History
The Dunedin Astronomical Society began as the Otago Astronomical Society at a University of Otago meeting on 27 September 1910. The founding meeting took place in the Chemistry Room, where R. Gilkison became president, Rev. P. W. Fairclough and J. M. Garrow were elected vice-presidents, Thompson Lamb was appointed honorary secretary, and W. S. Wilson honorary treasurer. In 1911 the organisation affiliated with the Otago Institute and operated as its astronomical section. A report the following year recorded a membership of 254, indicating that organised interest in astronomy was already well established in the region. The society initially lacked a permanent observatory. For a short period around 1915 it maintained a Telescope House on Tanna Hill, within the University of Otago grounds. University development requirements forced the organisation to look for another location. A site near the Dunedin Botanic Gardens was considered, but the First World War delayed construction. In 1920 the society settled on the Belleknowes site that became home to the Beverly-Begg Observatory, completed in 1922. The observatory became the centre of the society’s public and member activities. The organisation promoted astronomy and telescope making, arranged lectures and practical demonstrations, and provided members with access to society equipment. In 1948 the Telescope Makers’ Club requested use of the society’s facilities and later merged with it, strengthening the connection between observational astronomy and hands-on instrument construction. An annex added during the 1960s provided improved space for meetings, talks, and telescope-building work. The society expanded its observing resources beyond the city. In 2002 it gained access to a cottage near Middlemarch, which serves as a darker-sky site for members. In 2013 piers were installed there for Sky-Watcher EQ6 telescope mounts. The site also supports a magnetometer and data logger whose measurements are used in solar-wind research by Dr. Yuki Obana of Osaka Electro-Communication University. DAS formalised its legal and charitable status in the twenty-first century. It became an incorporated society in 2000 and was registered as a charitable society by the New Zealand Charities Commission in 2009. Its programme continues to combine public access and member activity: meetings are generally held on the first and third Tuesday of the month outside January, with talks at the first meeting and practical observing or equipment work at the second. Winter Sunday public viewing sessions are held at the Beverly-Begg Observatory, and educational or private groups may arrange visits. The society’s members have also contributed to observational programmes. Occultation work has used the observatory’s C14 telescope, a Watec astronomical video camera, and an IOTA-VTI timing system. A SBIG ST8300M camera has supported astrometry and photometry. On 29 June 2015, members recorded an important Pluto occultation shortly before the New Horizons flyby. The society celebrated its centenary in 2010 through a programme that included hosting the Royal Astronomical Society of New Zealand conference at the Otago Museum, a commemorative public meeting in the original founding room, historical site visits, and the unveiling of a plaque near the site of the first meeting and early Telescope House.
