We have today added a sidebar to the Star Viewer video map. The sidebar contains links to each of the videos on the map. It is now far easier to navigate the map and find the individual stars and galaxies.
There is still a bug in the Google Maps API which means that the map acts strangely if you try to zoom in past zoom level ten.
If you have Google Earth 4.2 or above you can also view the videos in Google Sky. Download the Star Viewer Kml here.
