Hi Folks,
A topical subject given the total lunar eclipse taking place tonight-given clear skies.
This is a prime example of 'real time' astronomical imaging as you see it 'live in real time' no processing//stacking etc. video. My own feelings now is that the lines have become blurred in regards to what is real time video, now that we have cameras capable of longer exposures and stacking on the fly etc. Not a debate I want to start nor offend anyone. Each to his/her views on this subject.
Broadcast live round the world via the Discovery TV Channel, from the Southern Cross Observatory. in Tasmania, one of three participating southern hemisphere observatories.
'The Imaging Source' German camera manufacturer, donated the 1/2" CCD colour camera for the event-they certainly were well rewarded with the global advertising. This image was the best of the three observatory productions. The image filled the frame sharp and clear.
To do this production via a film maker in Melbourne took weeks of preparation to get a fast enough Internet upload speed for the duration of the broadcast (this was 2007) and Internet in Tasmania was a little faster than dial up at the time. Many real time trials had to take place over several nights to make sure it would all work. Things have improved since those days. An exciting project including doing an interview live to camera before the event started. A friend of mine was thoughtful enough to watch the program and take some screen grabs, something I could not do. It was a hectic few hours but so rewarding.
Hoping for clear skies tonight in Tasmania and for the rest of Australia...
