I came across this cool bit of astronomy software the other day. There seems to be two versions about sky-map.org and wikisky.org. They seem to be identical. They allow you to slide around the night sky with or without constellations and to search for your favourite night sky objects (like NGC galaxies), so far, so like any other planetarium software. The cool thing with this software is that it also has the SDSS imaging survey built in. So you can switch to SDSS mode and look at the actual images produced by the Sloan survey. Unfortunately the SDSS doesn't cover the whole sky so many of my favourites aren't in it.
This is really only the start, we have been talking about software like this at work for awhile now, the ultimate (wet) dream for astronomers would be software like this that started in planetarium view but over layed survey areas from the various surveys, or even little symbols to show where the HST had been pointed at an object (The first steps have been made to do this in the Astro Photo section, check it out). You would then be able to click on the little links to take you directly to the data, it would make life much simpler than searching dozens of archives to find out if what you would like to do has already been done, saving time and money for eveyone, plus it would make a great toy for everyone to enjoy.
Give it a go, there's probably plenty of weird things to be seen in the SDSS images.
