Since I'm dealing with very large FITS files (~400MB/file) and having to plot small sections from lots of those files, it takes an awefully long time to build an aplpy.FITSFigure out of it. As far as I know, there is no possibility to tell FITSFigure to load only a certain part of an image, e.g. by something like
```f = pyfits.open('bigimage.fits')
scidata = f[1].data
fig = aplpy.FITSFigure(scidata[1:100, 1:100])```
or the like. I don't know if it's possible, but it would be very helpful.
