Dec 17 @ 8:00 pm - 10:00 pm

This week’s talk: Christian Hettlage

The SAAO Open Nights in Cape Town take place on the second and fourth Saturday of every month at 20:00.

All Open Nights will start with a presentation on topics of astronomy or physics. Then, visitors will be given an introduction to the historic McClean telescope, the observatory museum, and the library. If the weather is clear, there will be a chance for stargazing using telescopes set up for the night.

Please email enquiries@saao.ac.za if you have any queries regarding bookings and tours for Cape Town Open Nights.


Christian is a software engineer at the SAAO, developing tools for the Southern African Large Telescope (SALT). He came to Cape Town in 2006 after completing his PhD in Germany.

At the end, you might not have the definite solution, but at least plenty to speak about at your Christmas gathering…
