Otago and Upper Clutha schools had a sneak peek at the Winterstellar Exhibition at Central Stories Museum and Art Gallery in Alexandra earlier this month.

Pupils saw the works featured a day before the exhibition opened in the Henderson and Grant galleries on July 3.

The opening came after a hardy band of children and adults braved sub-zero temperatures to celebrate Matariki in Pioneer Park behind the museum.

Inside, educational and fun activities were offered, with the assistance of the Otago Museum Science Outreach team.

The opening event was also the prize-giving for the inaugural Winterstellar Astrophotography Competition.

The winners were selected by a judging panel including New Zealand journalist and author Naomi Arnold, and US-based astronomer John Barentine.

Overall winner was Michael Cookson for his work Waipapa Point Lighthouse, which can be seen on a large metal print in the exhibition.

Winterstellar is an exhibition of astrophotography and videography about space, the stars and what we see from our place among them.

Winterstellar shares photographic works by both experienced photographers and those just starting out.

The exhibition runs until September 5.
