I've been able to use shots of the night sky as image targets, but I'm wondering if someone who views the constellation it from - say - 100 miles away might be able to track it. Also, I'm using an Evo, which has a higher-end camera, so I am not sure if the lowerend 5MP's can do the same.

Has anyone tried using constellations as targets? Have you been able to try it from multiple locations?

The perspective on the constellations will be very close at 100miles, but nearer objects will shift (e.g. the moon).

Here's a configurable map of the night sky - http://www.fourmilab.ch/yoursky/
You can see that there isn't much difference for a few degrees change in the position of the observer.

I would be surprised if any of these devices can pick up enough starlight to track off of, but I can't say for certain. Can your device take crisp pictures of stars in the night sky? Even if it can, when the image is downsampled for tracking you might lose too much information. We're talking about a relatively sparse image, at least where I live ;)
