This is a fish-eye view of the centre of the Galaxy region in Sagittarius and Scorpius nearly overhead before dawn on an austral autumn morning in March 2024. The Milky Way stretches from Aquila at bottom left to Crux and Carina at upper right. The aboriginal Dark Emu made of dark dust lanes in the Milky Way is here fully visible with the head of the Emu being the dark Coal Sack nebula beside the Southern Cross at upper right. The galactic core area made yellow from interstellar dust absorption contrasts with the bluer spiral arms to either side of the core. The pre-dawn Zodiacal Light brightens the sky in the east at bottom. It can be traced across to the other side of the Milky Way at top as the Zodiacal Band along the ecliptic. This is a stack of 4 x 4 minute tracked exposures, at f/2.8 with the TTArtisan 11mm full-frame fish-eye lens on the filter-modified Canon EOS R at ISO 800. It was on the old iOptron SkyTracker. The camera had an Astronomik clip-in UV/IR Cut filter in place which with this lens actually improves and sharpens its off-axis images when the filter shifts the infinity focus point inward. Taken just before thin clouds moved in to spoil subsequent frames, on March 14, 2024, from the Warrumbungles Mountain Motel near Coonabarabran, NSW, Australia, at the 2024 OzSky star party.
