Star motion
The universe is not static and the stars are in constant motion.
Most move so slowly that we can scarcely notice it, but a time lapse photo can
show some shift.
The animated GIF below compares the image of M33 taken on
the 7th October, with an image from the Digital Sky Survey. At least two stars
have a displacement that is visible.

some time to load)

More Star motion
Here is another one I found. The bright star in the image is Beta Andromeda (Mirach)

The importance of stacking images.
The image on the left is a single frame - the best one of 60
separate images. All 60 images were stacked together using Registax, to
produce the image on the right.
Some wavelet sharpening was then applied.
The improvement in detail is very obvious.
The weather vane is at the top
of St John's Church in Bromsgrove. Note that the wind produced some rotation of
the cockerel, so his tail feathers appear twice in the stacked image. The
Church is 2000 feet from my back garden.
