As for determining minimum camera spec, the NASA link calls for the Lumenera
LW230 monochrome machine-vision camera.

So 2 MPixel with 12 fps will get you in the ballpark.

A quick Google turned up
OpenStarTracker http://openstartracker.org/, ;
which looks real interesting.
According to the forum, it can
run on a BeagleBone Black, but I haven't
been able to find anything on minimum camera
specs.
