This weekend, the skies above Tāmaki Makaurau (Auckland) decided to give us a clear night during this rainy spring. Since I was in the city, II used my L-eXtreme narrowband filter hence the red colour you see. First time with this filter, and am happy with my progress towards my Orion Nebula summer project.

I hope you enjoy, and have a wonderful day!
