Combine 9 Photos Together with PowerPoint

On the evening of December 25th, I came to Hsinchu - we call it the Windy City. Because of the strong wind in winter, there are many wind power plants on the coast. Fortunately, the sunset next to the windmill and the formation of Ω Sun (Sun Inferior Mirage) happened to be recorded. It is very interesting that the windmills on both sides are running normally, but the windmill next to the sun turns very slowly for some reason, forming a very interesting video. Combining photos is to organize several important processes together, hoping to show the process of Inferior mirage formation. At the same time, with the windmill as a reference, it is easy to observe the shift to the right (north) at sunset.
The video link of Ω Sun and the windmill is as follows: https://youtu.be/CXCXa1SRm4k. The video was shot from 5:10:27 PM to 5:14:15 PM, for a total of 3 minutes and 48 seconds. Plays at 3x speed of normal sunset.
