News on what’s been happeing in BAS.
Openstax.org is an initiative of Rice University that provides free educational materials to students world-wide. In January 2020 Openstax published a web version of their textbook – Astronomy. This text provides an excellent introduction to many aspects of astronomy, from the fundamental science to galaxies, quasar, black holes and beyond. This is an excellent resource for anyone interested in learning more about astronomy. Get web access to the book here.
Saturday July 18th, 2020, a memorable night.
COVID-19 has delivered us a very disrupted year. BAS hopes all of its members, and their families, have escaped the worst aspects of the disruption and everyone is safe and well. However, we have all been starved of telescope and astro-camera time under the stars in recent months. But last Saturday night delivered at least one form of antidote to our frustrations.
Our members conducted members-only observing evenings at our Maleny Golf Club and Harding’s Paddock sites. The sky was exceptionally clear and steady – exactly what we needed. Both sites were well supported by members and the planets put on a show for everyone.
Maleny plans to conduct another members-only night on Saturday, July 25th. So, start packing your gear. You might just get to glimpse a comet too.
Congratulations to Dr Ken Wishaw for being recognised by the Queensland amateur astronomy community for research into human eye dark adaptation and the effects of red/amber light on adaptation speed and effectiveness. During 2018 Ken conduced research with volunteer astronomers at the Queensland Astrofest and Sunshine Coast BAS astronomy evenings, held at the Maleny Golf Club. His research found that the common red-wavelength light astronomers have been using for decades to protect night vision and speed dark adaptation, may not be the most efficient wavelength for in-door and at-the-scope lighting. Ken found that a more amber/orange wavelength may in fact be a better option. Read more on the details of Ken’s research HERE.
Ken was recognised for this research at the 2019 Queensland Combined Astronomy Societies meeting held on December 6th at the University of Queensland. Well done Ken.
Ken also delivered an excellent talk at the meeting outlining the formation, objectives and recent achievements of the Australasian Dark Sky Alliance. Ken is one of the founding members of this initiative to help protect the night skies of Australia from the ravages of light pollution. Again, well done Ken.
The South-East Queensland Combined Astronomy Societies annual meeting was held on Friday December 6th at the University of Queensland. BAS is very proud to announce that two of our most hard working members – Tony and Anne-Louise Surma-Hawes – were recognised by the Queensland amateur astronomy community for their many years of commitment and effort invested into the planning, delivery and management of the annual Queensland Astrofest event. For many years, Tony and Anne-Louise have been the BAS representatives on the organising committee for this multi-society event. Tony and Anne-Louise put in countless hours each year, that BAS members never see, to make the Queensland Astrofest one of the most highly regarded astronomy festivals on the planet. So, a very big thank you to Tony and Anne-Louise. May the Astofest-force continue to be with you for many more years to come.

Astronomy in Antarctica. It seems a strange place to locate a telescope. Most of us find a SE Queensland winter a sufficient challenge to operate a telescope. However, BAS member, Mike Zupanc, who has actually lived and worked in Antarctica, explained to us just why the frozen continent is one of the best places on Earth for a few specific forms of astronomy. For one, the atmospheric turbulence we experience in temperate and tropical zones from jet streams and moving high and low-pressure systems and pestering clouds, are not an issue on the high dome regions of central Antarctica. Moisture is also never a problem as it instantly freezes to ice on the ice pack. So, telescopes are free of dust and condensation and can even track circumpolar objects continuously at certain times of the year. We even learned that the University of NSW has an entirely autonomous telescope operating in Antarctica. That is an impressive feat. Most of us have enough trouble keeping our telescopes operating for a few hours within arm’s reach.
Thank you Mike for a really informative talk.
After a 2018-19 summer that delivered little rain, but clouds just about every New Moon period, we finally had a win. BAS held its second 2019 Dark Sky Weekend at the Warwick Gliding Club (WGC) on Saturday 4th and Sunday 5th of May. It looked doubtful leaving Brisbane in a drenching storm on Saturday afternoon, but the forecasts proved correct and the skies cleared for two fantastic nights under the stars and rising Milky Way. The WGC facilities were excellent and club members extremely welcoming. The only disappointment was the dismal show by the Eta Aquarid meteors. Let’s hope we now get a good run of cloud-free New Moons for the remainder of the year.
