[AstroPy] Source Extraction from Star Trails?

Does anyone know of a program that produces selected star trails on a az 
equal-distance projection of the sky?  Ultimately, it would be good if 
the program could match these trails against composite (long exposure) 
all-sky (fisheye) images.  From that data, it would be useful to produce 
the location of the north celestial pole, north azimuth position, and 
possibly the zenith.

Aside from possible star catalog need, one would need to supply 
lat/long, start time of trails, and maybe 5-10 stars that require trails 
for some specified time.
