Hi Rob
In the early 1990's a set of chatrst for both clouds was generated by Matti Morel. You can find details at

These Charts are fantastic and the best thing to have when observing the clouds. I have been using them for over 15 years and used the SMC chart for my SMC web page observations.
You can also use the Herald Bobroff Astro Atlas as they also have quite detailed maps for both clouds.
NONE of the computer programmes come close to the detail in the Morel charts.
Hope this helps
Andrew
