It's OK. The gentleman who did the show, Roy, was really good, but unfortunately the chairs are really uncomfortable. The projector is a whopping 91 years old, which is something to behold in itself, but unfortunately, the show we watched is probably almost as old 😀 (Seriously though, it must have been from the 90s; I think it's about time to update it). We've been to the Planetarium in Cape Town as well, where the guy doing the show was really poor, but the overall experience, comfort of the chairs and the visuals, were a lot nicer. It's a pity, because I think this could be a nice attraction. It's high time that the Wits Planetarium gets an upgrade.
