They do a lot of cool and clever stuff - for example for the partial solar eclipse in August, it was not well observable from their grounds, as it was happening low above the horizon near sunset. So they rented a hot air baloon, which even launched from a meadow next to the Planetarium (which is often used for hot air baloon launches during the summer) and then they live streamed the eclipse for as long as possible - IIRC about ~5 minutes longer than what was possible to see on the grounds. the Stream recording is here, end to end from baloon launch to night landing in a field: https://m.youtube.com/watch?v=wWrs-36nvg4&pp=0gcJCVgCo7VqN5t...
