The exhibition is currently at Toa Payoh Public Library, Level 2, near the newspapers section. Not sure when the exhibition will end there and be shifted to another national library.
Being a stargazer, love the starscapes photo there. Glad the star trail photo won the People's Choice!
Those astronomy related entries were shot overseas. No doubt, it is impossible to shoot Aurora in Singapore but I think it is still possible to shoot some nice starscapes in Singapore for those who are patient enough to wait for clear skies and fast enough to react to such skies when it happens. Of course, one need to acquire the unique skills and experience required to do astrophotography as the constantly rotating Earth throws up some interesting challenges in keeping stars sharp and focused in long exposures.
