Normally yes, but I guess this is a very complex illusion.
The neighbor objects, like the sun, moon and planets in our solar system, are visible moving faster and easier to measure. Even the larger distance star systems like Mintaka (delta orionis). The double stars are orbiting each other in less then 6 days and is measurable on a distance of 700 light years from Earth. The galaxies are not 'moving' because of their distance, millions and billions of light years.
