Asteroid?

[Ampthill]

I was imaging the Orion nebula last night, I noticed a line in the bottom right of the image.

The exposure time was 20 sec, with a Skywatcher 72ed.

It shows up on 9 images

Could this have been an asteroid?,  It seems too slow for a satellite!.

Any thoughts would be great!

That'll be a geostationary satellite.

They orbit high above the equator, so that from northern latitudes they appear a few degrees south of the celestial equator due to parallax. Which is why they so often appear in images of the Orion Nebula and other objects at a similar declination.
