Actually this is commonly called the Horsehead Nebula but it reminds me more of a seahorse than the land variety, so I've decided that it should be renamed!
It was difficult to process due to the brightness of the star Alnitak in the field (different colour halos, vanes, ghost reflections), but it seems to have turned out OK in the end. All data collected with the Bunyip 12.5".
