Trying to do set_xlim on the axes with a defined projection raises an
error "It is not possible to change axes limits for geographic
projections. Please consider using Basemap or Cartopy." So, try basemap?
http://matplotlib.org/basemap/ It's fairly geographic-specific but
should be bendable. (Don't know if it's possible to label RA in hours
instead of degrees longitude.)
