Allegheny Observatory hosts an Open House once a year. During the Open House, more of the building is opened to the public. Instead of having a tour guide, you will follow a designated tour path around the building.
Both of the main telescopes will be outfitted for visual use and the members of the Amateur Astronomers Association of Pittsburgh will be setting up additional telescopes on the front lawn.
The 2018 Allegheny Observatory Open House will be held on Friday, September 28. The Open House is free, but you must reserve your tickets by calling 412-321-2400.
