On a visit to Yosemite in May of 1975 or 1976, I saw a very clear, very dark and moonless night sky that was studded with stars. I gazed at the sky for a long time because it was so beautiful, and in that sky I also saw galaxies. I don't remember exactly how many galaxies, but there were multiple galaxies. As I gazed at it, I thought to myself that I would probably never again see such a sky (I was right) and that for the rest of my life I would doubt that I had seen such a sky (I was right). I kept gazing at it, to fix it as much as possible in my memory. Still, the memory is elusive. My sense is that there might have been twenty or more galaxies in that sky. Would twenty or more galaxies visible to the unaided eye have been possible forty-five years ago? Elevation about 3500 feet, clear dark night, 1975-6.
