Stargazing WorldWide Telescope

It's OK, but you get less overhead and more flexibility if you will use other resources with non-unified interfaces. Like the Canadian Astronomy Data Center for example. You can also do batch queries. http://www2.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/cadc/

In our M51-type galaxy association project, we relied heavily on IRSA, with its DSS, SDSS, and 2MASS front-ends. DSS was the most useful, and comparative observation between blue, red, and infrared bands helped us identify structure in the galaxies. Active star-forming regions tend to look more luminous in blue, as do HII galaxies, and the older materials tend to be luminous in the red bands. Also, we used the DSS plate scans in reverse grayscale, since that makes faint structure stand out more readily than positive images.

I use it almost every day. A very satisfactory resources for no cost... it is indeed big though.

 

What do you download that is 2Gb+? Jesus, that's huge...

 

When you connect, the overhead is pretty impressive. If you connect to IRSA, the connections may not be really fast, but they are pretty reliable.
