Questions

The best nights are Wed 5 May, Thu 6 May, Tue 4 May, Fri 7 May, Mon 3 May, when the sky is fully dark and the moon is down for most of the night.

Not really: in May the galactic centre is below the horizon or only up in twilight or moonlight.

Weather is not included. Times are local (America/Edmonton).
