| Update: Hi resolution image also available here

| Since I'm a complete noob at astronomy, I wanted to ask a couple
| of basic questions about the image:
|
| 1. What causes the bright flares/flashes around some bright
| starts/galaxies?
|
| 2. What are the elongated traces that look as if the telescope
| moved/rotated while capturing the image?
|
| 3. Why do some of the smaller flares seem to be doubled (e.g. 3
| stars in the top-right corner of the image)?
|
| Thanks in advance to anybody patient enough to explain.
