In 1910, Walter Goodacre published a map of the Moon, created over the course of several decades using nothing more high-tech than a good quality backyard telescope. Goodacre was an amateur astronomer. He didn't have access to top-of-the-line observatory. But he did have a knack for detail and willingness to painstakingly record his observations of the Moon with pen and paper, eventually producing a map that's accurate to a few kilometers. (In contrast, the high-definition images that we get today from lunar orbiters show details at a scale of a few meters.)
University College London has an explorable version of Goodacre's map on their website, along with scans from his 1910 book that broke the map up into sections. (As art, the sections are almost more intriguing than the full, stitched-together image.) It's all part of a larger collection of historic space images, photos from the Moon, Mars, Jupiter, and Venus.
