Zodiacal Light and Skyglow

At first glance this image just shows the orange glow of light pollution on the horizon. However the neutral colour of the Zodiacal Light, extending upwards and leftwards through the middle of the image, shows that it is not the same thing. The colour difference wasn't perceptible to the eye but being able to sweep the eye across the area made it easier to distinguish Zodiacal Light from the background.

Combining two images allows more of the sky to be shown and the contrast between the Zodiacal Light and the rest of the sky becomes more apparent.
