Toward the Centre of the Galaxy
This is without a doubt the most spectacular area of sky. Here we’re looking toward the centre of our Galaxy, toward the starfields of Scorpius (at right) and Sagittarius (bottom centre). The field is a riot of stars, dark lanes of dust, and patches of glowing red nebulas.
It is wonderful experience – wonder-filled! – just to lie back and scan these constellations with binoculars or a wide-field telescope. One outstanding feature are the parallel bands of dark dust that seem to form the shape of a dark prancing horse in the Milky Way.
The brightest area of the Milky Way here is the Sagittarius Starcloud, and marks the direction of the centre of our Galaxy. From here in Chile where I took this shot, this region of sky passes directly overhead, making it more prominent than at northern latitudes where the galactic core is often lost in horizon haze.
This image is a stack of four 6-minute exposures at f/4 with the 35mm lens and Canon 5D MkII camera. For one of the exposures I shot through a special soft-focus filter to add the fuzzy star glows that make it easier to see the outline of the constellations. The filter also emphasizes the colours of the stars.
The image is a segment of a 12-section panorama I shot all along the Milky Way from dusk to dawn.
