It is the light-gathering ability. Most objects in astronomy are very faint or, at the very least, benefit from being made brighter than they appear to the unaided eye. The light-gathering ability of a telescope depends on the diameter of its primary mirror or lens, which is often called its aperture. All other things being equal, the more aperture you can get for your money, the better the telescope.

The only problem with Scorpius and Antares, for many of us, is their southerliness and therefore lowness in the sky.
