Lost in the Milky Way

Just lie back and lose yourself in the Milky Way.

That’s what one person is doing here, under the starry skies of Cypress Hills, Saskatchewan. In summertime the Milky Way is the main attraction at night. Here, it rises from the south, a region containing the centre of our Galaxy in Sagittarius, to climb up overhead through the star clouds of Scutum and Aquila, then into Cygnus in our local spiral arm, and on into Cassiopeia at the top of the frame in the north.

As in most deep sky photos, I’ve boosted the contrast and colour to make a dramatic image. To the eye the Milky Way appears in subtle shades of grey painted with the dark brushstrokes of dust lanes winding through the bright clouds of stars. But your eye does see much of this structure.

I like these types of ultra-wide images. They capture the mind’s eye impression of what the Milky Way looks like across the vault of heaven.

This is a stack of four 5-minute exposures, all tracked on a small equatorial mount, the Kenko SkyMemo, and all taken with the Canon 5D MkII at ISO 800 and Canon’s ultra-wide 15mm lens at f/4, as you can see from the photo data at left. I retained the ground from just one image, to minimize the blurring from the slowly moving camera tracking the stars. I masked out the ground in the other 3 images. They help smooth out noise in the sky.
