Yep, it is really cool, only tried it a couple of times so far, so still working my way through it.
Erick, the site is at (
www.slooh.com) i think you can get a free 7 day trial.
Ken, no mate i cant connect the 5D, now wouldn't that be good.
But i did reserve a 5 minute block to view some nebula, once you have booked it it is your spot, until you have used the time, and you can reserve time many days in advance and look at anything from the Planets to Globular Clusters and so on.
