Messier Catalog Interactive Options

We hope that this page will once become a rich resource, but currently it contains only three small applications:

Random Viewer for the Messier Images: View a random Messier object. By Guy "Smiley" McArthur.
Access the Messier Objects Directly (searchable Index) (doesn't work currently)
Identify galaxies in the heart of the Virgo cluster interactively
