Perth Observatory on Mount Eliza (1896)
Fig. 1. Old Perth Observatory on Mount Eliza (Wikipedia 3, Nachoman-au)
The Perth Observatory on Mount Eliza is the oldest in West Australia, founded in 1896, and opened in 1900. "The residence for the Government Astronomer was designed by architect George Temple Poole in 1896, while the dome building to contain the telescope was designed by Sir Howard Grubb the following year."
In 1965, due to air pollution, the observatory was moved to the New Perth Observatory in Bickley. The old observatory dome was demolished in the 1960s.
The first activities of William Ernest Cooke (1863--1947), director from 1896 to 1912, were time service (Standard Time for Western Australia), tides, meteorology, and support to surveying. A time ball was dropped at 1 p.m. daily at the Round House at Fremantle and in Hay Street, Perth, and in addition a time gun (1902) was fired at 1 p.m. at Perth and Fremantle. Time signals from two clocks were sent out by telegraph, also for the railway network.
Perth Observatory was involved in the international project, started in Paris in 1887, first the Astrographic Catalogue (AC), constructing a catalogue of the position of millions of stars, the second, and second the Carte du Ciel (CdC), translating the AC to charts of these catalogues with the result of a "Map of the Sky". The Declination zone (-32° to -40°) was assigned to Rio de Janeiro Observatory, but because the work at Rio had not progressed until 1900, the task was assigned to the Perth Observatory.
The observing/photographing was done from 1900 to 1920, but because of many problems with the amount of material, the work continued until the early 1970s for publication; the AC was completed, the CdC was never completed. "Due to financial issues, 6 volumes were published by 1916, the remainder between 1948 and 1952 with assistance in measuring by Royal Edinburgh Observatory." (Craig Bowers, 2019). The photographic glass plates that are stored today at the Perth Observatory.
In 1901, Perth also participated in the international star cataloguing and charting project, the "Cape Photographic Durchmusterung" (CPD). A Catalogue of 420 Standard Stars was published by the Perth Observatory in 1907.

Right: The diameter of the round stellar image was measured with the "Irisphotometer" and the number was punched.

Main research topics of the new Perth Observatory in Bickley are again compilation of the largest southern star catalogues like the Perth catalogues (1976 to 1983), the photographic astrometry on minor planets and comets, and the participation in a worldwide observing program on solar system planets.

Especially interesting are the Perth catalogues, like the Perth 70 catalogue (1976), Perth 75 catalogue (1982), Perth 83 catalogue (1983), based on the Hamburg meridian circle, working in Perth since 1967. Erik Hoeg introduced the photon-counting astrometry as the basic measuring technique in Hipparcos, a technique invented by the author in 1960 in Hamburg. This technique was implemented on the Repsold meridian circle for the Hamburg expedition to Perth where he worked during 1967 to 1972.

State of preservation
The Old Perth Observatory at Mount Eliza is used by the National Trust. The house of the chief astronomer of the old observatory remained today. The astrographic dome of the old Perth Observatory was demolished in 1964.

Comparison with related/similar sites
Old Perth Observatory has a similarity to Sydney Observatory with the main building and a tower, in addition, a separate dome.

Description of (scientific/cultural/natural) heritage
Perth Observatory on Mount Eliza (1896)
Fig. 1. Old Perth Observatory on Mount Eliza (Wikipedia 3, Nachoman-au)
The Perth Observatory on Mount Eliza is the oldest in West Australia, founded in 1896, and opened in 1900. "The residence for the Government Astronomer was designed by architect George Temple Poole in 1896, while the dome building to contain the telescope was designed by Sir Howard Grubb the following year."
In 1965, due to air pollution, the observatory was moved to the New Perth Observatory in Bickley. The old observatory dome was demolished in the 1960s.
The first activities of William Ernest Cooke (1863--1947), director from 1896 to 1912, were time service (Standard Time for Western Australia), tides, meteorology, and support to surveying. A time ball was dropped at 1 p.m. daily at the Round House at Fremantle and in Hay Street, Perth, and in addition a time gun (1902) was fired at 1 p.m. at Perth and Fremantle. Time signals from two clocks were sent out by telegraph, also for the railway network.
Perth Observatory was involved in the international project, started in Paris in 1887, first the Astrographic Catalogue (AC), constructing a catalogue of the position of millions of stars, the second, and second the Carte du Ciel (CdC), translating the AC to charts of these catalogues with the result of a "Map of the Sky". The Declination zone (-32° to -40°) was assigned to Rio de Janeiro Observatory, but because the work at Rio had not progressed until 1900, the task was assigned to the Perth Observatory.
The observing/photographing was done from 1900 to 1920, but because of many problems with the amount of material, the work continued until the early 1970s for publication; the AC was completed, the CdC was never completed. "Due to financial issues, 6 volumes were published by 1916, the remainder between 1948 and 1952 with assistance in measuring by Royal Edinburgh Observatory." (Craig Bowers, 2019). The photographic glass plates that are stored today at the Perth Observatory.
In 1901, Perth also participated in the international star cataloguing and charting project, the "Cape Photographic Durchmusterung" (CPD). A Catalogue of 420 Standard Stars was published by the Perth Observatory in 1907.

Right: The diameter of the round stellar image was measured with the "Irisphotometer" and the number was punched.

Main research topics of the new Perth Observatory in Bickley are again compilation of the largest southern star catalogues like the Perth catalogues (1976 to 1983), the photographic astrometry on minor planets and comets, and the participation in a worldwide observing program on solar system planets.

Especially interesting are the Perth catalogues, like the Perth 70 catalogue (1976), Perth 75 catalogue (1982), Perth 83 catalogue (1983), based on the Hamburg meridian circle, working in Perth since 1967. Erik Hoeg introduced the photon-counting astrometry as the basic measuring technique in Hipparcos, a technique invented by the author in 1960 in Hamburg. This technique was implemented on the Repsold meridian circle for the Hamburg expedition to Perth where he worked during 1967 to 1972.

State of preservation
The Old Perth Observatory at Mount Eliza is used by the National Trust. The house of the chief astronomer of the old observatory remained today. The astrographic dome of the old Perth Observatory was demolished in 1964.

Present use
The Old Perth Observatory at Mount Eliza is now home to the WA branch of the National Trust.
Astronomical relevance today
In 1965, the observatory was moved due to light pollution to Bickley, 337 Walnut Rd Bickley, Kalamunda WA 6076 (32°00’28’’S 116°08’09’’E),
35 km East of Perth in Bickley (new Perth Observatory: Code 322, 323) - 61cm reflector.
The Florian asteroid 3953 Perth was named in honor of the observatory.
