You are invited to the Annual Open House at Allegheny Observatory when more of the Observatory is open to the public. Instead of having a tour guide, you will be following 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 2019 Allegheny Observatory Open House will be held on Friday, October 4. The Open House is free, but you must reserve your tickets by calling 412-321-2400.
