The question seems completely absurd to us in the 21st century: should we use cameras to help with astronomical research? Well, of course. Why wouldn’t we? But in the early 20th century, this was a heated debate that echoed in the domes of many established observatories around the world. So when did the camera really outshine the eye for documenting things in space?
