Hi,
I'm not familiar with astronomy, but I think I must learn more about the Disney-Von Braun[1] fairy-tale... I would like to know if somebody has a link to a good picture of a geosynchronous satellite aligned with the moon ? All that I can find are pictures of a simple flash of light[2]. I think that it should exist. The resolution of the picture of the Apollo 11 landing site[3] on google should allow us to clearly see a 1m x 1m object (does this picture been taken from ground ?). Geosynchronous satellites are 10 times nearer to the earth than the moon, and their visible face[4] should be a bit bigger than 1m x 1m. Nasa can track 0.1m x 0.1m orbital debris[5] from ground, what is the minimal size of a geosynchronous object that we can see from earth with a telescope ? .... while writing I've done a search, I found that a 1200mm telescope[6] can on only view geosynchronous objects bigger than around 15m[7], and a cheap 200mm around 100m objects. The biggest 10000mm telescope[8] can only view 2m objects... Does anybody with access to the biggest optical telescope of the world took a picture of a radio-communication satellite ? Thank you in advance for any information. Regards, Jean-Marc L.
