There was one big advantage to having only very high priced illumination. You could see the stars. I am reminded of trying to locate Messier objects (nebulae and galaxies and such) cataloged by their namesake. He used and instrument which I heard described as the equivalent to a broke binocular if you smeared Vaseline on the lens, from Paris. Now I had a twelve inch telescope in the far outskirts of SF, and I could find less than half of them. One mans gain is another mans loss.
