Thanks for rechecking on Sky View Cafe

I went and took the check marks off North on Top and East on Left, and found three possible candidates, working from nearest the planet outwards were Tethys (III), Rhea (V) and Titan (VI). Remember the Earth's moon was very full at that time and not far away from Saturn, so were the two outer moons washed out because of the lunar brightness, is the inner moon too small to see? I only saw one moon on the night, which of the three could it have been - and why?

Here is another problem, I was in reality facing North and had the East on my right, so why should I uncheck these boxes on the Sky View Cafe program? Is it that it is as a telescope sees it, in reverse?

I would assume that you 'WOULD' check the boxes to coincide with what your true position is, but as you know with the checks on, it does not correspond with what I saw at 1.00am on 4/2/07 from a Western suburb of Sydney. When I take the checks off, it seemingly is correct. Can you explain this?
