Whanganui was blessed with a clear, still night on Wednesday, as a blood supermoon - the first since 1982 - made an appearance in the sky.
Wanganui Astronomical Society secretary Mark Lee said around 50 people "ambled through" the Ward Observatory to use their telescope.
"It was a significant event, and while we haven't seen one like that for 40 years, it does happen reasonably regularly," Lee said.
"It's just not always convenient, but last night's was very convenient.
"It was directly overhead."
