The multiple star Sigma Orionis just right of centre, near the Horsehead Nebula in Orion, and with the Flame Nebula, NGC 2024, above. This is a stack of 8 x 5 minute exposures with thr 130mm Astro-Physics refractor at f/6 with the Canon 6D (not modified) at ISO 1600, plus a single 1-minute exposure added in for the bright stars to prevent them from being blown out too much. Even the long exposures were kept short so as not to overexpose the star too much — the focus was on the stars not on going deep to bring out the faint nebulosity. Shot Feb 17, 2017 from home. Some light cloud added glows to the stars.
The southern Milky Way from Canis Major to Carina, including Puppis and Vela and the large Gum Nebula complex, an interstellar bubble blown by stellar winds. Sirius at at right and Canopus at lower left. The open cluster NGC 251t6 is at far left. M41 cluster is left of Sirius. This is a stack of 4 x 2 minute exposures at f/2.8 with the 35mm Canon L-series prime lens and filter-modified Canon 5D Mark II at ISO 1600. A pair of stacked exposures taken through the Kenko Softon filter added the star glows. Taken from near Coonabarabran, Australia, April 2014.
The region of the Milky Way in Puppis and Vela encompassing the vast Gum Nebula, a photographic object only. Sirius and Canis Major are at right; Canopus in Carina is at bottom. The False Cross and the open cluster NGC 2516 are at left. This is a stack of just 4 x 3-minute exposures at f/2.8 with the 35mm lens and filter-modified Canon 5D MkII at ISO 2000. Incoming clouds prevented more exposures. All on the iOptron Sky-Tracker. Taken April 20, 2017 from Tibuc Gardens Cottage, Coonabarabran, Australia.
