Decades ago, when I was beginning my journey as a stargazer, I found myself at a so-called "night sky experience" in a remote location that, on paper, ticked every box. We were a small group — enthusiastic, hopeful and excited, having driven into the middle of nowhere to meet an astronomer. We were all standing under a dark, protected sky.But there, on the rise as the session began, was a big, bright, just-past-full moon. There was no Milky Way, and just a few bright stars clung on.People were polite. Someone asked where the Andromeda galaxy was. We were shown a very faint smudge in a telescope, which was then pointed at the moon. Within 20 minutes, people were drifting away.
