# Photo sources

The photos the binocular and telescope view shows on its photo card, one per object
(a star, a deep-sky object, the Moon or a planet),
shown beside the view and never inside it. Chosen by hand in `scripts/data/photos.yaml`,
built by `scripts/build-photos.py` (resized to fit 1024 px, JPEG quality 85, otherwise
unchanged). Each photo's credit is shown with it on its card.

Share-alike (CC BY-SA) photos are shown unchanged, only resized: no crop and no other
edit, which CC BY-SA 4.0 section 2(a)(4) says is no adaptation (our reading, not legal
advice). They are shared under their own licence, linked below.

ESA/Hubble, ESO and NOIRLab images are CC BY 4.0 under their sites' terms pages
(<https://esahubble.org/copyright/>, <https://www.eso.org/public/copyright/>,
<https://noirlab.edu/public/copyright/>, read 2026-10-27); each credit is copied from
the image page. Commons photos were fetched as 1024 px renditions through the Commons
API; their licence and author are those on the file page. Where two objects share one
photo (M42 and M43, Barnard 142 and 143) it is stored once.

The Moon and planets' photos are the `body` entries; each has its own caption, shown
under it. Mars's is ESA's CC BY-SA 3.0 IGO image (its page says the content can be
used under that licence or ESA's standard one; read 2026-10-29). Mercury has none: the
one ESA frame found carries the ESA and JAXA logos, whose use ESA's terms reserve.

Method: PNG files with transparency are composited onto black when converted to JPEG
(a format conversion with a black background, no other change). Affected: Barnard 142, M13, M36, M5, NGC 5139.
