The mass it takes to make a rigid alt\/az mount is substantially less, leading to cost savings. Unlike German Equatorial mounts, there are no meridian flips to deal with, and no  large protruding counterweights to create a dangerous hazard in a public observatory. Alt\/Az is more intuitive to use and no polar alignment is needed.
