I recently went for a visit to the Palomar Observatory and decided to spring for the extra $5.00 to go inside and get a tour of the Hale Telescope. Worth it – this is a photograph from inside the dome. With a 200″ mirror, the Hale Telescope was the largest in the world when it was inaugurated in 1948 – while no longer the largest, it is still in use 300 days per year for research purposes, generating valuable data. If only most technology lasted that long! I wish you all a wonderful and relaxing Sunday evening.
