Hi Dennis

The Octans asterism or trapezium rotates around the SCP approx once every 24 hours and so will move or rotate during the night.

Also, if you view the asterism at the same time each night, the position of the asterism will change (rotate) in the field of view of the PAS with the season of the year as well, just like the constellations.

Cheers

Dennis
