Thanks to a collaboration with my friend Stephen Voss, we present this composite image, taken over 3 nights last week. With Dunedin's Mount Cargill Tower as foreground, It shows the change in altitude of the sun over 3 nights caused by Earth's axial tilt and our motion around our parent star. It also shows the rotation of the sun over 3 Earth days (look at the sunspots and how they change position). Photos by me, processing by Stephen Voss. I love collaborations! #astronomy #NewZealand #sunset
