I've uploaded version 1.2 of the galaxy map. This has a lot more detail in the region of the Milky Way visible from the southern hemisphere, including 124 new molecular clouds and more than 70 new large HII regions - mostly from the RCW catalog.
I've also added a lot more images. There is now an image for each of the 313 objects in the Sharpless catalog, and I've created a specialised gallery for the Sharpless nebulae.
