I may be wrong, but what I think that means is amateurs who use their professionally made scopes to take photos of huge areas of the sky will have pictures similar to this, although I can’t recall seeing one processed to look like that.
Professional astronomers, using their “monster-sized” observatory scopes will take photos of extremely small areas of the sky, but with much more magnification.
There are many research grade scopes that provide wide angle field of views.
And speaking of wide angle..
“WASP or Wide Angle Search for Planets is an international consortium of several academic organizations performing an ultra-wide angle search for exoplanets using transit photometry. The array of robotic telescopes aims to survey the entire sky, simultaneously monitoring many thousands of stars at an apparent visual magnitude from about 7 to 13.”
