The Coalsack nebula as seen under New Zealand skies, 2024

This year was the first one I ever experienced the Southern hemisphere night skies! And what a beauty this sky is! Full of stars, nebulae and galaxies. A magnificent night sky. What impressed me as well is how dark this dark nebula from the pristine dark skies of New Zealand. A dark hole in the night sky, blocking all the ancient starlight near to it! 24 photographs were taken in 2 nights and stacked together, from Kaikoura and Raglan, New Zealand during my recent campervan trip around the South and North Island. No AI enabled software was used, just traditional methods of calibrating the light frames, aligning them and stacking them using PixInsight. Photoshop was used for colour balance mainly and final touches.
