A moving sky for an astronomy club open night
Event-page notes for amateur astronomy groups that want their observing-night announcement to show a slowly turning sky.
Astronomy societies hold public observing nights several times a year. The announcement page usually carries a single star photo, and a few seconds of the sky drifting overhead suits the topic.
Use a club member's own image
A wide-field shot of the Milky Way over the observing site is ideal, because visitors will see the same horizon.
Ask for slow rotation
Stars should drift, not streak. Mention "slow sidereal motion" in the prompt.
Look for invented objects
Generators like to add bright extra stars or a moon that was not there. Members who know the constellations will spot errors, so compare against the original.
Put practical details in text
Date, time, parking and a cloud-cancellation policy belong in plain text below the image.
