I'll take a shot at your challenge.
An amateur CCD astronomer John Lenard Walson has somehow been able to image objects that in many cases look like orbital spacecraft/stations. Some claim they are alien, but aliens would likely not have such clunky put-together objects. So these might be what you are asking for.
See this ATS Thread last year. I re-posted the images, but the videos are off YouTube now. So here is one that works.
Episode1 - F.A.S.T.
Also: Strange Things Above
He is imaging something. He seems to have some intuitive sense on how to find these. If you see his image of the ISS you will see that at the magnifications he is looking that there are many objects much larger than satellites and more the size of the ISS but in amazingly different configurations.
Unless you believe in Aliens (many of us do) and these could be, but are more likely orbital testbed, operations by a secret space program.
