The array will thus simulate a giant, single telescope much larger than any that could actually be built. (scienceinschool.org)
The VLBA, a series of 10 individual telescopes located at sites across North America, can create, in effect, an enormous single telescope with an aperture thousands of kilometers wide, thus providing the resolution necessary to probe the relatively small region at the core of our galaxy.

The next giant leap was optical interferometry, merging the light beams from two or more telescopes to create, in effect, a single telescope as large as the distance between the two. (discovermagazine.com)
