Thanks, but I'm not sure why people keep bringing up DS9. As I understand it, it is a stand alone program of sorts that has no interface with Python. It seems to me it would be like saying use Word or Adobe Photoshop.

J I'm not sure if I posted this reply already to this thread, or if it was the same topic on a different thread: You can also try pysao to comminicate with ds9, the interface is nicer (although the implementation might not, I don't know). http://code.google.com/p/python-sao/ >>> import pysao # run new instance of ds9 >>> ds9 = pysao.ds9() >>> import pyfits >>> f = pyfits.open('test.fits') # display first extension of fits file >>> ds9.view(f[0]) Note also, that there is the kapteyn package which uses matplotlib (pylab) to display the data from fits files according to the wcs (World Coordinate System) contained in most fits files in the correct way. http://www.astro.rug.nl/software/kapteyn/ Cheers, Stefan   Phil Hodge wrote: >> The question is whether ds9 is a module that can be used within a Python >> program?
