Good night to show the size differences of various Solar System objects thru a scope at 100x magnification. Images were taken less than 1 minute apart.
When the Gallilean Moons are close together you can easily see that Callisto is the dimmest and Ganymede is the brightest of moons. Io is hiding behind the planet!
