2. The fewer telescopes you have, the simpler the shape of the details you can recover (I'm tiptoeing around a lot of math here).
At radio wavelengths we can digitise the signals captured by the telescopes, and then do the interference in a computer. So you can have lots of telescopes.
But the VLT Interferometer works at much shorter infrared wavelengths where this is not possible, and the interference happens for real, in an "analog" way, which limits the number of telescopes we can have.
