Skywatching at Observatory Park, April 24, 2020, Telescopes & the Hubble Space Telescope

Turn your eyes skyward and enjoy the amazing sites from Observatory Park, home to the historic Gaithersburg Latitude Observatory.

Observatory Park will be dark, but please do not bring a bright flashlight; bring a red light as it will be less intrusive to other watchers. Red cellophane will be available to cover any white light flashlights. Also adjust the brightness of electronic devices.

Limited parking for those with accessibility tags is available onsite. Parking is also available at the field at the corner of DeSellum & Rt. 355 – 2 blocks from the park. No amenities available on site. Alcohol is not permitted at events in City parks.

Events at Observatory Park could be cancelled or modified at the last moment if conditions, including inclement weather and cloud cover, are not conducive to Skywatching. Please check the Community Museum Facebook page for last minute announcements.


  • Telescopes & the Hubble Space Telescope
    Friday, April 24, 2020 • 7 – 9:30 p.m. - CANELLED
    Celebrate Hubble’s 30th anniversary with an evening that is all about telescopes. Learn how to use them – either your own or one of the Observatory’s. Discover how telescopes work & explore the field of astrophotography. Tour the park & Observatory (starts at 7 p.m.) and participate in hands-on activities. With the help of staff from the Space Telescope Science Institute, see the kind of data that telescopes like the Hubble send back for research.

    For help using your own telescope, please contact us in advance to let us know what kind of telescope you have, so our volunteers can be prepared. You may call 301-258-6160 or email

Additional Skywatch programs may be planned depending on weather, staffing, and public interest. Please contact the Gaithersburg Community Museum to express interest in additional Skywatch programming.
