Question

Quizplus · Accepted Answer

The question states that the first improvement on observing objects through telescopes used a method other than relying on the human eye. The option that matches this description is photographic film, as it was used to capture images of objects seen through telescopes and allowed for longer observation times and better analysis of the objects being observed. The other options (projection systems, digital cameras, and polyspectral scanners) were not used in the early improvement of observation through telescopes.
