Hello Achim,

Very nice pictures, but not every amateur (radio or astronomy) has
a 1m telescope with fast moving positioning available.

The only way to see any details of AO-40, I think, would be to follow 
the concept of SSTL with their SNAP-1 nanosatellite (6.5 kg mass,
V RX, S TX, GPS RX, attitude stabilisation with momentum wheel,
cold gas propulsion, CMOS video camera etc.) which was put in 
orbit together with Tsinghua-1 and Nadezhda. The basic problem
here was to achieve a rendezvous with Tsinghua-1 after separation
due to very different drag coefficients. And they were running
out of propellant. Ever heard of such a thing ? ;) 
For details see proceedings AMSAT-UK 16th colloquium , SNAP-1 by 
Craig Underwood G1WTW et al. 
For a companion of AO-40, the main problem would be to achieve
exactly the same orbit, although drag problems should be minor.
