August 29 2006 - Satellite or Asteroid?

On August 29, I was photographing M11 with my 10" LX200 and canon G3 digital camera when I noticed that on three photographs of the many that I took of M11 to stack and process showed a small trail indicating a slow moving object. So I decided to create the following animation of the object as it moved across the feild of view. What do you think it is? When I showed this animation to one forum, they all agreed that it could be an asteroid because of the fact that the object took about a minute to move across the FOV in other words it moved too slow to be a satellite. But then When I showed the same animation to another completely different astronomy club, they seem to all agree that it was a satellite. perhaps a geostationary satellite because if an asteroid was moving that fast it would have to be very close to earth. Originaly I figured it was a satellite but remain uncertain of what it could actualy be. The first picture was taken at aproximately 9:38 EST on August 29 2006 from Mississauga Ontario. The reason why there is so much noise in these frames is because these are raw frames. The only processing done was to darken the background and try to brighten the stars and trail so to be more evident. Resizing was also done. On the middle frame you will notice that half of the picture is extreamly noisy, this is due to the fact that I have been taking many pictures at 15 secs each and thus building up heat on my camera and for some reason when my camera heats up once in a while a pictures comes out half noisy. Unfortunately it had to happen just as the object was going across the feild!

Stats for this animation:

3 x 15 second exposures @ ISO400, no zoom, F3.2

Meade 10" LX200 SCT, scopetronix 40mm MaxView plossal, Canon G3 4MP digital camera.

ImageJ was used to reduce background glow, Advanced GIF animator was used to make animation.
