Which specific telescope did Edwin Hubble use atop Mount Wilson?

Answer

100-inch Hooker Telescope

Edwin Hubble required immense light-gathering power to resolve the faint stars within the Andromeda Nebula, an effort that established its distance scale. This capability was provided by the 100-inch Hooker Telescope, which was situated atop Mount Wilson. This powerful instrument allowed him to probe these distant smudges in unprecedented detail, making it possible to conduct the necessary analysis of variable stars within the nebula.
