Unless there was movement of the camera during the observation then parallax does not explain the Boomerang shape.

The line if it was several different shots would still be in a straight lin not and arc.
The pic is a composition of several long exposure shots with a viewpoint change between them. The long exposure shots are making it appear as a line, the angle is due to the viewpoint change between these shots.
At least that's what I think we are looking at.edit on 19-8-2013 by NeoParadigm because: (no reason given)
I was also wondering, would the tail not have responded to the exposures as lines also instead of seeing the diffused light as we do?

Parallax was not meant to explain the boomerang effect. The effect is because of change in camera perspective.
Parallax only explains why the stars appear in the same position as if no change in perspective took place.
At least that's the theory.
They didn't change position durung the shots. I think the 3 lines represent 3 different long exposure shots from 3 different positions of Hubble.edit on 19-8-2013 by NeoParadigm because: (no reason given)

The Hubble 'scope is in orbit... thus always moves... right? Everything in the galaxy is moving, too, and beyond.
In fact, every piece of matter we know about is moving... but I digress... and digress...

Well, supposedly Deep Impact has pictures as well, not released yet, of course.

Though as usual with an interesting thread like this, the answer is lost in the noise (my noise included).
Tsurfer2000 found the NASA explanation that it's a conglomerate construction of three photos (with shutter speeds that create the long effect)... back around page 9 or so... the "frankenphoto" blurb... it doesn't mean it can't be discussed and the pic is very neat and it was a great find (kudos to the fiancee') but the three photos explains the three lights well... and the distance of the background stars explains why they aren't light lines, too.
The symmetrical arrangement is peculiar, but those details are explained, too, or were when I read it and was more alert hours ago.
For what it's worth from this professional amateur.
