Field notes
The map supports place search, direct map selection, and a “Use my location” control; date and hour can be stepped with arrow keys. Visibility settings use civil, nautical, or astronomical twilight cutoffs, while Uranus and Neptune are listed when visible but remain off by default because they need binoculars or a telescope. The page says official Street View overlays are typically accurate within 1° and flags user-submitted imagery as potentially highly inaccurate.
