http://www.wikisky.org/This "Wiki" astro site is the most advanced I've ever come across. Click on the right side and get stunning astroshots that look like Hubble photos as the star map in the center takes you there. Then magnify or decrease.
Move your curser to the icon in the middle top that shows the current time and click to input your location - it will show you a detailed sky map of your own sky above. It has a + - tab on the left corner to zoom in or out, just like Google map. Click on any object and get a whole array of pics to look at. Input a search and goto any object. Try a search for "M5" globular cluster and click on that to see unbelievable pics. Try some of the other features too.
I still go outside to view my own black and white "real" photon light stuff with the telescope. But this sites is for knowing what it really looks like. Go to areas of the sky where the galaxies hang out and magnify. Unreal.
Just 20 years ago this site would have been science fiction magic.

It lets you take snap shots of the screen too. Here's a cluster of galaxies I just "discovered" as I rambled around the sky... The bright glare is a closer galaxy - while the distant ones are 400 -600 million light years away. Gonna name it the "Dr. Love Cluster"
