This list is for any discussion associated with Python in astronomy,
e.g. FITS modules, Numeric enhancements, statistics packages,
telescope control software, etc.

In my earlier days I wrote a data acquisition program for the Univ of
Cape Town photo-polarimeter.  It ran on 286-class computers under DOS.
Since discovering Python, I thought it would be an interesting project
to rewrite it using Python with C-extensions for controlling the
hardware.  Python would give the developer a capability similar to
Forth, in that you could control the hardware (eg, a stepping motor)
interactively at the command line for testing purposes.  I think it
shouldn't be too difficult and would be a valuable asset to create a
library of C-extension modules for hardware control: everything else
such as data reduction and graphics can be done in Python.

Let me know if I can be of any help.

Cheers,
Paul
