  • Support – All the lines that should be vertical (the dome aperture, the silo-type things) are. I think the mountains really do just slope downward like that. Moonreach (talk) 16:33, 30 October 2024 (UTC)[reply]
    I double-checked, and the silos aren't truly vertical, although they're close. The exterior vertical elements on the observatory base are, though. It's possible that there really is a tilt here, but if there is, it's much more subtle that then horizon line suggests. Moonreach (talk) 19:41, 30 October 2024 (UTC)[reply]
  • To illustrate the camera rotation in this photo as per discussion above, I don't have a lens correction profile for the drone used here, so the perspective lines won't quite match. ro|3ek (talk) 13:23, 31 October 2024 (UTC)[reply]
  • Sorry, I disagree. The camera is pointing northeast. Google Earth here and here and the elevation map here confirm that's the natural slope of the mountains. In the screenshots, the observatory is at the center of the red circles. Some mountainous skylines just aren't horizontal. Bammesk (talk) 01:14, 1 November 2024 (UTC)[reply]
