I did a little while ago, but the installation process was so daunting on my Mac that I never ran it. I don't get the impression that things have changed.

It goes both ways so supports the feedback of you getting an ra/dec from a position on the plot as well as putting markers and lines on the plot using ra/dec.
Any simple example code? This has to be one of the simplest examples I can think of.

That looks good (my problems with matplotlib notwithstanding), but `import from __future__` doesn't actually work like that. :)

We have a winner! APLpy takes it for ease of installation (normal process) and clear examples on the web site.
gc = aplpy.FITSFigure('V1.fits')
gc.show_markers(187, -72.73, edgecolor='red', facecolor='red', marker='o', s=10, alpha=0.8)
Would have preferred that ra/dec were named parameters, but that's just being picky.
