Comet Hartley 103P

Finally I had a decent view of it.  Took a long time to find, partly because I didn't realize it was moving fairly quickly, so an ephemeris even 20 minutes out of date had a visibly off position.  What I could see with my 8" at around 68X and 150X was a diffuse oval glow, about a minute of arc in diameter.  The center of the glow was about a minute of arc away from the predicted position, which also threw me off.
