OK Dennis.
I have looked at your images from several angles. Blinked them, Neg'd them, adjusted contrasts etc.

Fed them into astrometrica to produce the returned image.
Details gained;
Time of start 4-10-08 at 22:26 EST
Time of exp 30min
Cooling ~-12
Focal length of system -bloody close to 1339mm
Camera orientation 89.7deg ie top of frame is east.
The red cross indicates the measured centre of the frame.
**the FITS header indicates a "lunar filter"?

Now the good news,
I believe, from Guide 8, that the object in the indicated position IS Sycorax.
It has the correct position and direction of movement.
The second frame you sent was ever-so-slightly focus shifted and drifted, (I have that same problem often) so image is very difficult to see due to its extreemly low level of registration.

In short, I believe you have imaged Sycorax.
Well done and congrat's.
