The historic transit of Venus is tomorrow (6 June), starting early in the morning. While some of you will have taken time off work (or made simple observing devices to take to work), not everybody can do this. Also, your locality may be clouded out. Webcams to the rescue!
The iconic Siding Spring Observatory will have a live feed courtesy of iTelescope.Net, the Research School of Astronomy and Astrophysics and the Australian Astronomical Observatory. The web-cast will start on June 6, 2012 at 8am local time at Siding Spring (June 5, 2012 at 22:00 UTC). http://www.ustream.tv/channel/itelescope
The Royal Institute Australia will also have a live stream: http://riaus.org.au/events/livestreaming-of-the-transit-of-venus/
As well there are a number of public viewings.
If you still want to make some projection systems, then there is a step by step guide for making a cheap binocular projection system here
and how to know where to point your telescope when you can’t look through the viewfinder. http://astroblogger.blogspot.com.au/2012/05/okay-so-how-do-i-point-my-telescope-at.html
And don’t forget the excellent Venus Transit Series here at the conversation.
