  1. Palomar Observatory, Southern California

    About a million times easier than last weeks contest.
    Do you have any idea how many orange colored roofs there are in cities across the Netherlands, Belgium, Italy…? It was very challenging (good) I just wish I had had more time last week to search.

  2. This is the Palomar Mountain Observatory on Palomar Mountain in north San Diego County, California.
