Description:
Historically, observatories were as simple as containing a sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Modern astronomical observatories typically contain one or more permanently mounted telescopes contained in buildings with a rotating or removable dome.
Expanded Description:

  • The 'Astronomical Observatory' must be a permanent facility.
  • A permanent mount for the telescope is required, minimally a pier for the telescope.
  • Observation buildings should have a movable overhead structure, though radio observatories will clearly be an exception.
  • Please make a single entry for observatories with multiple telescopes.
  • Active and retired facilities are welcome.

    It is your responsibility to obtain permission of the owner before waymarking a private observatory.

  • Instructions for Posting a Astronomical Observatories Waymark:

    REQUIRED:
    Include a default close-up photo and an area photo of the observatory site taken by you.
    Additional photos with proper credits may also be posted.
    -- Please do a search for additional information and fill in the variables as completely as you can.
    -Check the requirements on the previous page before completing this page.
    Instructions for Visiting a Waymark in this Category:
    Note the time of day of your visit, and your own photo of your favorite part of the observatory. This might be the view from the observatory, picture of your favorite building or favorite exhibit. (Be mindful of flash photography rules!)

    If you participated in an observing session, let everyone know what you saw!

    Astronomical ObservatoriesGaithersburg Latitude Observatory

    in Astronomical Observatories

    One of six world-wide latitude observatories built in 1899. The precise nightly star measurements from here were used to prove and monitor the "wobble" of the earth on its north-south axis. Satellites replaced these observatories in 1982.
