If you're planning on heading out to our observatory ...

  • The observatory is located at 18850 W Observatory Rd in New Berlin. It is on the north side of the road, 1.1 miles west of Calhoun Rd and .7 miles east of Racine Ave at the top of the hill. Usually we have a sign out at the entrance. For complete directions, click here.

  • Weather is always a factor.  The months of April, September, and October can be cold, especially at night. Either dress warm or prepare by having coats, hats, and even gloves.  Expect mosquitoes in June, July, and August.

  • Viewing through the telescopes is also weather dependent, but we are open nonetheless. You may still come out and tour the observatory, get information, ask questions, and listen to the featured programs for the night.
