I took individual images of each star 60 seconds apart with ISO 16000 and speed 1/50, stacked them with StarStaX and presented them together to compare the differences in colours of the stars. The images are taken slightly out of focus to show the colours. The variations of colour are from the earth’s atmosphere which splits the light from the stars and the camera picks up the colour flashes.
