Of the three links (Elephant Trunk, Orion and Cone Nebula) Orion just blows me away.
The trick for me was to turn off any lights shining on the monitor, sit about 40 - 45 cm away from the screen and *relax* and go cross eyed. Once I had three images I only "focused" on the middle one. And if all else fails you can always follow the instructions.
Really deeeepp man
Good luck
ps the images are a slow load on dialup
