. We've heard them a million times, but we have no idea who said it first, it can NOT be attributed. 
"It moves"
Galileo considered his theory of the tides to provide the required physical proof of the motion of the earth.
Tamron 18-270 Di II lens
iso 50
F:5.6
1&1/2 hour exposure
S.B.S
A Rular area is a must for this kind of shots.
Big city's have a lot of "light pollution" & is impossible to capture the movement of the stars.
Find the scene that you like,compose,frame it & you are ready!
A tripod & a dslr with "bulb" function is a must.
Set the focus to "manual" & focus to infinity (so you have the Hyperfocal distance).The concept of hyperfocal distance is easy to understand: focus a lens at the hyperfocal distance and everything in the photograph from some near distance to infinity will be sharp. Landscape photographs are often taken with the lens focused at the hyperfocal distance; near and distant objects are sharp in the photos.
Try different settings (f number) but the iso should be the lowest possible!
3-5 shots are enough to get a good result.
Here you see 3 vertical frames of 30 minutes each.
Hope i help with this s.b.s & keep shooting.....

And, it's still a saying, not a quote 
I love shots like this, pretty wild to see the angle at which the earth spins, good job author.
Very nice!
I would like to say something but I really have no words. Numbers are not enough for my vote.
Absolutely beautiful Author! Is this a single 1 1/2 hour exposure or a sequence over an hour and a half? I only ask because I plan on doing some star trail shots soon and am trying to learn a bit more about them.
Looks freak'n awesome, I've never actually seen one of these shots with such a long exposure. Beautiful work.
Cool - I have been meaning to try & do some star trails too. These are Awesome
Love this. The foreground looks like a painting. Well done and Good Luck.
CONGRATS!!!!!
Congrats! I'm very new to photography so I'm influenced by a lot I see on here and this shot was the reason I made my first attempt at a star trail shot (I still have some tweaking to do). Very glad to see this do well!
Congratulations, stunning image
