Blink Comparison

Two simulated images of one field of view of the sky at two times are presented below.

All the sources are meant to be unresolved and the size only indicates brightness.

Most of the objects are stars and do not move relative to each other.

There is a planet that moves relative to the stars.

But just looking at the images one at a time it is hard to find the moving planet.

Can you just see it?



But if you blink quickly back and forth, the planet wiggles before your eyes.
