Queenstown man Verdun Waghorn was a UFO sceptic - until he photographed one.
Now he wants to know if the truth is out there.
A fortnight ago he was fossicking for rocks by the Dart River bridge on the Glenorchy-Routeburn road.
About noon, he took 20 photos of the surrounding landscape to show his family.
Looking through the images that evening, he noticed one showed a small, dark shape in the western sky towards the Humboldt Mountains.
