--- Quote from: Psawhn on May 05, 2008, 06:25:19 pm ---I know what you're saying, and I think that even to a space telescope, a distance of several hundred km is as good as infinity as far as focusing is concerned.

The part I'm skeptical about is not focusing on the UFO, but the UFO staying in the shot longer than a fraction of a second. Relative velocities even in LEO can reach past 14 kilometres per second (Mach 10, which doesn't apply in space as there's no air or sound in space, is only about 3.4 km/s). At any distance, if the camera can zoom in to visibly see the UFO, the apparent velocity (speed the object moves across the sky) will be too high to see more than a streak in a single frame of video. The camera would have to somehow be rotating at the right speed to track the UFO, then the UFO miraculously jumps in front of the camera.

Actually, maybe the best way to fix this is to not have the tracking camera be a space telescope, but some other, lesser, camera with a wide field of view. Considering the Hubble can see the moon at this level (top image), even my zoomed-in shot is way too wide of an angle to be of any scientific value in a photography mission.

--- End quote ---

Remember that the zooming-in is a digital enhancement of the image, not an actual refocusing of the telescope lens. The telescope itself was part of a program that reconfigured (nearly) all human space monitoring equipment to give as much coverage of the solar system as possible, so it's entirely plausible that the wide-angle setting of the telescope is part of that.

And if you consider how many terabytes of data a telescope in 2084 could store and transmit every day, there's really no restrictions to how much visual data it could absorb.

Sean_E:
In the end, Psawhn is correct.  Image focusing would be a secondary issue with the shear velocity of the object entering orbit being the first.

Psawhn:
I had to cheat a bit to increase the resolution. I actually increased the size of the carrier and the moon by four. See if you can spot the visual blooper this causes. :)

Winter:
To be honest with you, I can't tell. I much prefer this version to the previous one, though!

I fixed that little blooper, as well as getting rid of some annoying stars in the first shot, and also increasing the bloominess of the jump-flare.

If you have no objections, this will be the final version of the movie.

The visual blooper was the inconsistent location of the UFO relative to the moon at the point it jumped in. (The old video's still up if you want to take a look). In the wide-angle shot, the UFO appeared well to the right of the moon. In the zoomed-in shot, the UFO appeared while in front of the moon. This was because in the zoomed-in shot, the moon (and UFO) were actually physically enlarged, and the moon sort of 'reached out' to grab the UFO :).
