It's five photos in my video, not three, and NASA did release a version that only used one photo for the comet, and parallax is involved. That's why the line of the comet is bent. Parallax occurs as Hubble moves in orbit, which is both during and between exposures. The direction of the parallax is inclined to the direction of the comet's motion, so as the parallax occurs in one direction the comet appears to slow down as the line of its apparent motion is deflected. This causes the appearance of a hairpin turn before the parallax starts to go the other way as Hubble rounds the earth passing its farthest south latitude and starts going north, causing the comet to be deflected the other way and accelerate. You spent a day on this but you didn't actually do any analysis of what Hubble should have seen from orbit by celestia or any other program?
Quoting: Dr. Astro You are using parallax in an obscure manner as i read it.. Oh well, too bad, that's what it is. Parallax arises due to change in viewpoint but that can occur due to motion of the observer, or of that which is being observed, or of both. What is essential is relative motion. By observing parallax, measuring angles and using geometry, one can determine the distance to various objects.
The way I read your statements is that you seem to suggest the 'streaking effect' is the parallax effect when it is not, from what I can ascertain from reading about it, its the position of the comet in each frame that shows parallax. The shape is just the length of exposure... I am not sure if you are doing this on purpose or if its just the way you express yourself..
Quoting: ACQuit making this about "me." The position of the comet in each frame does show parallax, the linear motion of the comet is from its motion in space, but that motion is distorted by parallax, both deflected and retarded/accelerated at times. The biggest question is why nasa felt the need to stack these photos (3 or 5) and present them as the 'finished product' when the one of the comet which forms the "centre" of the "boomerang" shape would of sufficed to produce a wonderful shot and not cause such an uproar..
Quoting: ACWell they did both. I don't like the full stacked version either but it is what it is. NASA didn't hire me to do it. Maybe NASA should hire you! I try not to post bullshit and I try not to get mad when people run there holes even if I know what I post is true and they are wrong, But GLP is luckly to have you Dr. Astro, you don't bullshit around. But with all that said NASA does do some dumb shit, makes me think its just to get the people all fired up.
