Kitt Peak National Observatory Mayall 4-meter Telescope Tour
Posted: 28 October 2026
Cloudy skies returned on Saturday, 24 October 2026. The sky was clear Sunday night, 25 October, but I didn't open the observatory. The sky was clear on Monday night, 26 October, but I rested up for the next day's visit to Kitt Peak National Observatory.
Tuesday, 27 October, was clear. An astronomer friend and I drove two hours to Kitt Peak. It was a beautiful day on the mountain. Here are iPhone 15 Pro Max photos I took during our visit. We took the docent-led tour of the Mayall 4-meter Telescope.


















This was my 14th visit to Kitt Peak. See Visits to Other Observatories for those reports.
