>>184507 The moon is an obvious shoop. The star trails might be a composite, but there is really no reason for them to be, and if they are the exposures were taken one immediately after the other because the trails are continuous.
>to get a 24hr exposure/complete circles, you still need somewhere it is dark for at least 24hrs at a time. In order to get complete circles, you don't need to do a 24 hour exposure. It takes 24 hours for a single star to make a circle, but there are many stars and even a fairly short exposure with the north star in view will produce the appearance of complete circles.
Note the pic (taken from google image search) 1 hour exposure taken in New York, on ISO 100 Fuji slide film. http://www.guidescope.net/starfields/circles_50mm.htm
