23 magnitudes. Hubble isn't the only instrument capable of discerning such faint objects right now. There are ground-based telescopes, too - the ESO VLT Ultra Large Telescope of the Southern European Observatory in Chile. These are four 8-meter mirrors with adaptive optics and a common focus, so equivalent to a 16-meter mirror. And the adaptive optics reduce distortion caused by atmospheric turbulence.

Those smaller ones described are visible. Those that are lost in the light of their larger twins are separated by spectrum. And in fact there are such twin stars 6 at a time, they are separated by spectrum perturbations apparently. Hi
