It is, in fact, an image of the star beta Octans, very near the south celestial pole. The surrounding stars are readily identifiable using a star chart or planetarium program. The image was made by tracking on the star for part of the exposure, and then slewing away from it. Other star trails are not seen because the other stars are more than 100 times dimmer than beta Octans. Beta Octans is located 60? from the imager's target, NGC253. It is certainly difficult to explain how he could have made this error, since he explicitly says that he made 10-minute images of NGC253 both immediately before and after this supposedly aborted 9-second image. A 60? slew away from and back to a target is pretty hard to overlook...

I don't know if a long-term exposure of a satellite would result in a "wiggly" line, but if it is as Elton says, possibly the result of the photographic equipment used - well, any thoughts?
