Exploring the Stars: A Brief History
Early Astronomy and the Telescope
People have been looking at the sky for thousands of years! Ancient cultures watched the Sun, stars, and planets to create calendars for farming or special events. Early astronomers in places like Babylonia even figured out that some sky events happen regularly and can be predicted using math.
In ancient Greece, thinkers started to imagine the planets moving around the Earth in a 3D model. Later, scientists like Copernicus, Galileo, and Kepler showed that the planets actually orbit the Sun.
A huge change happened in the early 1600s when the telescope was invented. Galileo Galilei quickly improved it. In 1610, he used his telescope to discover four moons orbiting Jupiter. This was the first time anyone saw a moon orbiting another planet! He also saw that Venus had phases, just like our Moon. This helped prove that Earth moves around the Sun.
Later, Isaac Newton explained that the same force that pulls things to Earth also keeps the Moon in orbit. He called this the law of universal gravitation.
Stargazing in Australia
For over 40,000 years, Aboriginal people in Australia have observed the southern skies. They created amazing stories and beliefs about the stars, planets, Moon, and Sun. Many groups saw the Sun as a woman warming the land. The Moon was often seen as a man who grew fat and then disappeared, only to return.
Aboriginal people also used the sky as a calendar. They knew when to move to new places or find different foods. For example, the Boorong people of Victoria knew it was time to gather mallee-fowl eggs when the "Mallee-fowl" constellation (Lyra) disappeared in October.
European Astronomy in New South Wales
In 1768, Captain Cook sailed to Tahiti to watch Venus pass in front of the Sun. This observation helped scientists measure the distance between Earth and the Sun. On his way back, Cook mapped the east coast of Australia.
In 1788, the First Fleet arrived in Australia. A young officer named William Dawes, who loved astronomy, set up the first observatory in the colony. He hoped to see Halley's Comet in 1789, but he didn't. His "tent-observatory" was on a ridge that is now called Dawes Point.
Later, in 1821, Governor Brisbane set up an observatory in Parramatta. He had the best instruments and a science library. This observatory helped map the southern skies and was Australia's first big contribution to world astronomy.
In 1858, the Sydney Observatory was built. It was the first government-funded observatory in Australia. Other observatories were built in Melbourne, Adelaide, and Perth.
During the late 1800s, many amateur astronomers (people who love astronomy but don't do it as a job) started their own groups. They built their own observatories and made huge contributions. John Tebutt was one of these important amateurs. He even discovered a "Great Comet" in 1861!
Ken Beames: A Master Telescope Maker
Ken Beames, who built the Linden Observatory, was part of this amazing group of amateur astronomers. He was known as a "master" because he was so good at what he did.
Unlike most astronomers, Ken Beames loved designing and building telescopes and optical instruments. In the 1930s, 40s, and 50s, he was one of the only people in NSW making these tools. He made over 450 telescopes! This was special because most telescopes were imported from other countries back then.
Even though he wasn't a professional astronomer, Ken Beames' work was highly praised. His 24-inch (610 mm) reflector telescope, finished in 1939, was the largest amateur-built telescope in NSW for many years. It was also one of the first large telescopes in Australia to use electric motors to move the telescope and its dome!
Ken Beames also designed other optical tools, like a "blink comparator" for the Riverview College Observatory. This was probably the first one made in Australia.
Ken Beames' Life and Work
Ken Beames was born in Gilgandra in 1899. He started as a telegram boy and later became an electrical and mechanical engineer. In 1924, he started his own business, Ken Beames Engineering Company, making wireless sets and other electrical items.
In the 1930s, he started studying optics and math for his astronomy hobby. In 1934, he built his first telescope. He then began work on his famous 24-inch telescope, even making his own machine to grind and polish the glass mirror!
During World War II, Ken Beames used his amazing skills in optics to help Australia. He made parts for sighting telescopes and signal lamps used by the Royal Australian Navy and British Navy. He also made parts for Mosquito bombers.
After the war, Ken Beames wanted to move his big telescope away from Sydney's city lights. In 1948, he bought land in Linden in the Blue Mountains. His friend, Albert York, helped build the brick base for the observatory.
Over the next ten years, Ken Beames designed and built the dome and all the electrical systems, even winding his own special motors. He built most of the machinery needed for the telescope in his workshops on the property. By 1959, the 24-inch telescope was finally working!

Ken Beames was very generous. He often gave advice and materials to other amateur telescope makers. He also continued his manufacturing business, making parts for buses, which helped fund his astronomy projects. He even made unique items like a brass clock and a book with brass pages!
Ken Beames passed away in 1989. Today, the Linden Observatory is still used by amateur astronomers and for education, just as he wished. Observers at Linden have even discovered new supernovas (exploding stars) from this site!
What You'll See at Linden Observatory

The observatory is on a large piece of land in the Blue Mountains. The main parts of the complex include:
- The Observatory building, which holds the 24-inch (610 mm) reflecting telescope.
- Another building with a sliding roof that houses a newer 30-inch (762 mm) telescope.
- A machine shop where the planetarium instrument is kept.
- A sheet metal workshop, now used as a meeting room and for storing telescopes.
- Other buildings like a storeroom and a special constant temperature building.
- Open areas with concrete pads where other telescopes can be set up.
- Ken Beames' old house.
Most of these buildings are from Ken Beames' time and hold many historical items.
The 24-inch telescope is huge! It's about 2.74 meters long. It uses electric motors to move smoothly and follow the stars. The dome itself is 3.7 meters wide and rotates on 16 wheels, also powered by motors.
Inside the Observatory building, you can also see Ken Beames' first telescope from 1934. It's made of brass and is a beautiful piece of work. There are also cupboards with lenses and electrical equipment he built. The building also contains drawings and notes from his work during WWII.

The workshops contain machinery from the 1940s and 1950s. One workshop has special grinding machines Ken Beames designed to make optics for WWII. The main workshop holds the partly finished planetarium instrument and a brass clock. Ken Beames' planetarium is the only one of its kind designed and built in Australia!
There's also a modern 30-inch (762 mm) telescope built around 2002 for public viewing.
Condition of the Complex
The historic 24-inch telescope is still in good shape. The mirrors were even re-coated by the Mt Stromlo Observatory. Some of Ken Beames' custom electrical parts have stopped working, but the machinery in the workshops could probably still be used. His drawings and notebooks need care to keep them from degrading. Overall, the collection of tools, machines, and documents is very complete and in good condition.
Changes Over Time
- In the 1980s, Ken Beames made changes to the telescope's power system.
- A new power board was installed in 2008 after lightning damage.
- A 30-inch telescope was added in a separate building in 2002 for public use.
- Smaller 8-inch and 12-inch telescopes were bought in 2005 and 2007 for public viewing and education.
- The original storeroom burned down in 1977 and was rebuilt in 1978.
The Linden Observatory Trust works hard to keep the site going with the help of volunteers. Ken Beames wanted the site to be used for amateur astronomy and education, and it still is today!
Why Linden Observatory is Special
The Linden Observatory is very important to the history of New South Wales. It's a rare example of a 20th-century amateur astronomy complex. It includes telescopes, the observatory dome, and the workshops where Ken Beames made everything.
Ken Beames was an amazing inventor and engineer. He was one of the few people in Australia making scientific instruments in the early to mid-1900s. His work helped astronomy grow in NSW and Australia. The observatory also shows how professional and amateur astronomers worked together over many years.
Ken Beames also helped Australia during World War II. His skills in making optical parts were very important for producing military equipment.
His 24-inch telescope was the largest and most advanced telescope in NSW from the late 1930s until the mid-1960s. It was also one of the first in Australia to use electric motors to control the telescope and dome.
The entire complex, with its observatory, instruments, drawings, machinery, and documents, is a rich resource for learning about astronomy and engineering in NSW.
Important History
The Linden Observatory is important because Ken Beames' 24-inch telescope was the largest Australian-made telescope in NSW for many years. It's still considered one of the most important amateur-built instruments in Australia. Ken Beames made about 450 telescopes in total!
Special People
The Linden Observatory is strongly linked to Ken Beames, who built everything there. He was a master instrument maker. He also made the first Australian-made "Blink Comparator" for the Riverview College Observatory.
Ken Beames was highly respected by other astronomers. His skills were also crucial during WWII when he made optical parts for the Australian and British Navies.
Amazing Achievement
The Linden Observatory shows Ken Beames' incredible technical skills. He was a master at many types of engineering, including designing instruments, making mirrors, working with electronics, and building clocks.
Some of his telescope designs were very new for their time, like using electric motors to control the telescope and dome.
His planetarium, which he started in the late 1950s, was designed from scratch. It was the first and possibly only attempt to build such a large planetarium in Australia.
His workshop, with all its tools and custom-made equipment, shows how he solved complex problems. All the items he built, from telescopes to decorative brass objects, show his amazing craftsmanship.
Community Connection
The Linden Observatory is important because Ken Beames shared his knowledge with many amateur and professional astronomers. Many people visited the site and were inspired by his skills, leading some to careers in science and engineering.
Ken Beames wanted the site to be an astronomy education center. Today, it's regularly used by amateur astronomers and groups like the Western Sydney Amateur Astronomy Group (WSAAG) for observing nights and learning.
Learning Potential
The Linden Observatory offers great opportunities for research. We can learn about:
- The history of telescope making in Australia.
- How the Linden telescope was built.
- The making of optical instruments in Australia.
- The production of optical military equipment during WWII.
- The history of amateur astronomy in Australia.
The site continues to be a place for learning and practicing amateur astronomy and telescope making.
Rare and Unique
The Linden Observatory is rare because it's one of the few privately owned historic observatories in Australia. It's unique because of its complete collection of workshops, tools, and materials, all strongly linked to Ken Beames.
Amateur-built telescopes of this size (24 inches) with professional-quality mounts are still very rare. The 30-inch telescope at Linden is the largest publicly accessible instrument in Australia.
The observatory also has very good "dark sky" viewing, unlike the Sydney Observatory, which is affected by city lights.
The planetarium instrument at Linden is an extremely rare example of an Australian-made planetarium. No other site in NSW has such a complete collection of tools and materials related to the design and building of these instruments.
Key Characteristics
The Linden Observatory shows the best of astro-mechanical, optical, and other engineering from the 1930s to the 1950s. The collection is unique in its size, condition, and quality.
The work done at Linden, like discovering supernovas, shows the high-level contributions amateurs can make from a "dark sky" site.
The Linden complex is similar to "Stellafane" in America, which is famous for its role in amateur telescope making. Both were largely the work of one dedicated person.
