If they are solar observatories and we have only (1) sun it seems the focus would be on a shared subject ... No ?
The Hilltop Dome contains several telescopes that have one task only: to look at the whole Sun all the time that the Sun is visible. Pictures are regularly taken through these telescopes; most of the time at the rate of one picture per minute, but more if it is likely that something interesting will happen.
The Hilltop Dome telescope takes two kinds of pictures: ones that show what the Sun looks like to the human eye, and others at a particular color (with a wavelength of 6563 Angstroms) that is affected by hydrogen atoms in the Sun. In such pictures, faculae, filaments, and solar flares stand out much better than in ordinary pictures.
The Hilltop Dome form an archive of observations of the Sun. It allows scientists to see the largest possible number of interesting things on the Sun (such as solar flares), even if the other telescopes at the observatory are looking at other parts of the Sun.
