Early telescopes, developed in the early 17th century, typically featured a simple design with a convex objective lens and a concave eyepiece. The most famous early model, created by Hans Lippershey, was a long tube with glass lenses at both ends, allowing users to magnify distant objects. These telescopes were often made of wood and metal, with varying lengths and diameters, and lacked the sophisticated adjustments and coatings found in modern telescopes. Their construction was rudimentary, which limited their clarity and focus compared to today's standards.
In terms of inventions, the telescope would have made it possible to do this.
Look in the textbook
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.

A telescope.
Unless you have a extremely powerful telescope, a galaxy and a star look almost the same.
One that you look through, rather than into.
