Aperture Fever – does my mirror look big in this?

The guest for March’s Bath Astronomers’ gathering is Dr Julian Onions from University of Nottingham. His talk is entitled “Aperture Fever – does my mirror look big in this?”

After a very brief review of how telescopes work, we look at some of the existing telescopes, both visible and other wavebands, and consider why they are so big, what they can and can’t see and what the telescopes planned for the next few years will deliver.

The evening will kick off at 7:30pm on Wednesday 31st March and virtual doors will open at 7pm to allow people to chat. All welcome whether members, prospective members or those just interested in stargazing and space. The event will be run using Zoom and details are to follow.
