Because the nebula complex is angularly big, it is often imaged
using relatively short-focus photographic lens instead of astronomical
telescope. But the CielAustral group of astrophotographers (Jean Claude
Canonne, Nicolas Outters, Philippe Bernhard, Didier Chaplain, Laurent
Bourgon) used TEC 160 telescope with 112 cm focal length. It was necessary to stitch 9
images, each captured by large-format G4-16000 camera, to cover the
The resulting image has fantastic resolution almost 12000 by 12000
pixels (click the image for full-resolution variant). Also notice the
globular cluster M4 close to the upper-left corner and the much
smaller NGC6144 globular cluster, somewhat closer to the image center.
Total exposure time exceeded 67 hours.
