The photograph would record far more stars, nebulae, and galaxies than the naked eye could see. There are many thousands of such photographs to be seen on the web. Any camera capable of long exposures with an equatorial mount and a clock drive could create such a photograph. A clock drive, which turns the right ascension axis of the mount at the speed of a hour hand (hence the name), counteracts the rotation of the Earth.

What if the moon did not rotate around earth?
If the moon didn't rotate around the Earth, it would be to dark to see at night and eclipses would not exist!
How would a three-hour time exposure photograph of stars in the northern sky appear if earth did not rotate?
The stars would be brighter points of light. Without the Earth's rotation, the Earth would not be moving enough to create the lines of light that ordinarily appear in an uncorrected stationary time exposure. Depending on the clarity of the sky, the entire image could be grayed by scattered light (light pollution).

Do typhoons rotate clockwise?
In the northern hemisphere, typhoons rotate counter-clockwise. In the southern they rotate clockwise. This is due to the force of the rotation of the Earth.
How would a three-hour time exposure photograph of stars in the northern sky appear if earth is not rotating?
This answer depends on the location of the camera taking the picture. If the camera is on the ground, then the exposure would come out clearer if the camera was not mounted on a system that could automatically move the lens. If the camera was in LEO (Low Earth Orbit) it wouldn't matter if the earth was rotating.
How does the big dipper rotate around the north star?
Not just the big dipper but all of the stars appear to rotate around the North Star because Earth is rotating. The North Star does not appear to move because it is in line with Earth's axis of rotation.
Why do the stars appear to rotate around Polaris?
It's an illusion caused by the actual rotation of the earth.
