Too fast moving in a 25 sec frame Lee, I think, to be a geo.
More likely just a pesky polar or low orbit sat. The orientation of the track
would also reveal geo or non geo.
I have imaged geos with a modded webcam and they are much fainter and slower
than that.
Edit: see this
thread/
post for a similar image.
The speed of a typical polar satellite, passing through a similar exposure.
As for capturing geos: tracking off reveals them as a dot, stars trail...tracking on, they are almost impossible to image as they smear.)
You can calculate which band of declination you might expect the geos to be parked
over your location.
