In 2018 the University of the Free State (UFS) launched the historic 27-inch Lamont-Hussey Refractor telescope exhibit together with the completed observation platform and a garden in front of the Naval Hill Planetarium in Bloemfontein.

The re-installation of the telescope as a static outdoor exhibition at Naval Hill is now complete. The project started several years ago after the recovery of abandoned parts of the old telescope. What followed was a story of trial, patience, careful planning and a lot of hard work.

 

Taking it apart

According to Dawid van Jaarsveld from the UFS Department of Physics, the mounting and tube of the Lamont telescope has returned to its home, the Lamont-Hussey Observatory, for display. The telescope had 47 years of service and years of abandonment in the veld after it was taken apart in 1975.

Its former telescope dome now hosts the Naval Hill Planetarium, the first digital planetarium in Sub-Saharan Africa.

The telescope was taken apart after the observatory was closed in 1974. It was dismantled and the optics were sent back to the University of Michigan with the largest pieces “left for dead in the veld” on the grounds of the Ehrlichpark Fire Station.

According to Dr Hendrik van Heerden from the UFS Department of Physics, who assisted in the technical side of re-installing the telescope, the larger pieces were recovered by Braam van Zyl and subsequently moved into the museum hanger of the Bloemfontein Fire Brigade where they stayed for many years.

 

Contribution to science

The University of Michigan in the US built the Lamont-Hussey Observatory between 1926 and 1928 in Bloemfontein for the study of double stars. The telescope had great historic significance and was used by professional astronomer RA Rossiter from Michigan, who set the record for discovering and measuring more than 5 000 double stars. The planetarium also measured the most double stars in the world, more than 7 000.

Van Jaarsveld describes a double star – also known as a binary star system – as two stars orbiting around one another. Studies of double stars enable researchers to determine the mass of stars.

Earl Slipher used the telescope to take one of the very first colour photographs of Mars in 1939. Slipher took 60 000 photos of Mars in 1939, 1954 and 1956 with the telescope. He was the world expert on the planet at the time. The camera Slipher used is displayed in the Boyden Observatory museum just outside Bloemfontein.

 

Putting it together

Van Heerden continues: “In early 2017 the components [of the telescope] were relocated to Dukoc Manufacturing in Bloemfontein for cleaning, treatment and painting. It took a while, as the missing components had to be manufactured before the final painting could be completed. The missing pieces were made with the help of the original blueprints of the telescope, provided by Prof Patrick Seitzer of the University of Michigan.

“These blueprints, along with measurements taken from the cleaned parts at Dukoc Manufacturing were used by Barend Crous, UFS Head of Instrumentation, to develop and manufacture the missing parts. These include the polar axis (solid steel axle over 3 m long and weighing more than one ton), axis-bearing caps (cast-iron pieces weighing more than 100 kg and 200 kg respectively) and telescope position wheels and gear works. After the required components were manufactured and refurbished, they were relocated to the Naval Hill Planetarium for the launch ceremony which was held on 5 June 2018.

“Planning of the installation of the telescope thereafter started in earnest. The jigsaw had to be put together again. The sheer size of the parts required some heavy equipment during the installation. With hard work, good coordination and a bit of luck, a team consisting of myself as project coordinator and consultant, Barend Crous, site engineer; Innes Basson, supervisor; Denver de Koker, handyman; and Wikus Storm, welder, got the job done,” Dr Van Heerden said.

 

Information sessions

Astronomy enthusiasts, tourists, school groups and other members of the public can now visit the Lamont-Hussey telescope with it finally back home after many years of neglect and abandonment in the veld. It can again hold itself high, looking at the stars.

The official opening of the telescope will take place on 26 April 2019 and Prof Seitzer from the University of Michigan will attend the opening event.

The refurbishment of the old telescope and the establishment of the new garden and observing platform were made possible by a R1 million donation by ArcelorMittal.

Social work students off to Sweden on exchange programme

In 2011 the university signed an exchange programme agreement with Jönköping University (JU), in Sweden. Since the inception of the contract the UFS Department of Social Work has been able to send two second year students to the guest university for a semester annually while also hosting students from JU.

 

The UFS is one of only 350 partner universities that JU co-operates with on an international level. The university that describes itself as “the most international university on Sweden” welcomes 714 exchanged students annually. This year, their School of Health and Welfare will host two of our Social work students, Moratoe Tshabalala and Lettie Mohoko; who are the fourth duo to take this unique opportunity.

These Kovsies will join the JU from 17 August-20 December 2015. By focusing on Swedish Social work and welfare policy, participation and inclusion, and Old-age care, they intend to use the learning experience to influence our country’s welfare system.

Growing up in Wesselsbron - a small town in the Free State, Lettie has always been passionate about working with people and having a positive impact on their lives. She sees the exchange programme as an opportunity to gain an international perspective which will provide more skills, hence improving her community engagement.

Moratoe, who is from the small town of Senekal, echoed similar sentiments, adding that she is interested in the distinctiveness of Sweden’s social welfare system, which offers free education, where old people get free care from the government, and children get incentives to attend school.

Lettie and Moratoe also volunteer as representatives of the UFS at ENGO Family Care, a non-profit organisation in Bloemfontein.

Dr Anneline Keet, Head of the UFS Social Work Department, believes that the exchange experience enhances the students’ critical thinking, and facilitates their ability to engage with different social welfare systems. While only two students are able to experience the full exchange annually, the rest of the students also benefit from the discussions taking place in class where students from the guest university (JU) join them for a semester.
