Scope
This code is not yet ready for general release.
Open Star interactively reads multiple images of a fixed star field
from a designated directory structure, sums them, rescales the sum,
and displays it. This has the affect of maintaining the objects in
fixed positions ( stars ) in the summed image, while averaging away
sensor noise and transient objects ( planes, satellites, UFOs, etc ).
The program also supports normalizing hot pixels by subtracting out
a dark field image.
