In it, Kepler set out the theoretical basis of double-convex converging lenses and double-concave diverging lenses—and how they are combined to produce a Galilean telescope—as well as the concepts of real vs. virtual images, upright vs. inverted images, and the effects of focal length on magnification and reduction.
Much of the scientific work on optography was performed by the German physiologist Wilhelm Kühne.Inspired by Franz Christian Boll's discovery of rhodopsin (or "visual purple")—a photosensitive pigment present in the rods of the retina—Kühne discovered that, under ideal circumstances, the rhodopsin could be "fixed" like a photographic negative.

The compound eyes of the arthropods are composed of many simple facets which, depending on anatomical detail, may give either a single pixelated image or multiple images per eye. Each sensor has its own lens and photosensitive cell(s). Some eyes have up to 28,000 such sensors arranged hexagonally, which can give a full 360° field of vision.
The reference to a "new planet" would have been important to Keats’s contemporary readers because of the recent discovery of Uranus with a telescope in 1781 by William Herschel, Court Astronomer to George III. News of Herschel's discovery was sensational, as it was the first "new" planet to be discovered since antiquity. [8]
