But a little telescope costs probably about three orders of magnitude less than a big telescope and you can afford to hammer a particular target night after night, whereas you'd be lucky to have an hour of time on a large telescope.

Precisely why PCs/workstations revolutionized research/individual analyst computing.

Make no mistake, in prime focus photography the brightness of extended objects does not depend on the size of the scope, but the size of the generated image is still proportional to the size of the instrument.
