Hume Cronyn Memorial Observatory Doors Open London

Hume Cronyn Memorial Observatory

During Doors Open, visitors will have an opportunity to look safely at the sun through a solar telescope and view sunspots and prominences on its surface. Tours include the three history rooms that re-create the early days of the observatory with authentic artifacts. The observatory will also be open on the Saturday evening of Doors Open for public stargazing.
