Opening the 28-inch
Last year, after @media, a group of us met up in Greenwich on Saturday morning. I gave a rough guided tour, including the history of the Royal Observatory, John Harrison’s chronometers, the adoption of standard time and ended it all by opening up the 28-inch refractor.
If there’s interest, I’ll do it again this year. Leave a comment below if you want to come along.
