Synes også at der var lidt mange journalistenehder - men kunne selv godt lide den m. en golfbold på 25 km.

Ja, det er ret farverigt sprog - romanbladet og ikke et ingeniørmedie værdig. Ud over enhederne, så også uklart: golfbold på en given afstand siger ikke så meget, hvis man ikke kender linsens brændvidde (forstørrelse), og 40 gange månen: areal eller diameter?

.. kan måske bedre forstås, når man læser en anden beskrivelse:

The LSST Camera focal plane contains 3.2 billion pixels, each about 10 microns wide, and the focal plane itself is extremely flat, varying by no more than a tenth of the width of a human hair. This allows the camera to produce sharp images in very high resolution. The images taken by the LSST Camera are so large that it would take 378 4K ultra-high-definition TV screens to display one of them in full size. The focal plane is more than 2 feet wide, large enough to capture a portion of the sky about the size of 40 full moons—this will allow Rubin Observatory to image the entire Southern Hemisphere sky every few nights.

The LSST Camera’s focal plane has a surface area large enough to capture a portion of the sky about the size of 40 full moons. Its resolution is so high that you could spot a golf ball from 15 miles away. (Greg Stewart/SLAC National Accelerator Laboratory)

PS. Gad vide hvor "et billede af objekter, der fylder syv gange så meget på himlen som fuldmånen. " kommer fra?

Den må ikke variere med mere end en tiendedel af bredden af et menneskehår.
