All-Sky Milky Way Looking South (7.5mm Z6III).jpg
This is a capture of the entire sky on a single frame with a fish-eye lens, with the Milky Way in prime position arcing across the sky.
This was from home in southern Alberta at a latitude of 51° N on a perfect night with very clear skies and, remarkably, not much red or green airglow. And no aurora! Even so, the light glow from Calgary illuminates the sky to the west at right. The camera was tipped down slightly to the south to include the southern horizon at bottom, but cutting off the sky at top due north.
The dark dust lanes along the Milky Way stand out well, as do the bright red emission nebulas such as the North America Nebula overhead at centre in Cygnus. The bright galactic core area in Sagittarius is above the southwest horizon at lower right. At upper left is the Andromeda Galaxy, Messier 31; the smaller and dimmer Messier 33 galaxy in Triangulum is visible as a small smudge to the left of M31.
Saturn is the bright "star" at lower left. The subtle glow to the right of Saturn is likely Gegenschein — sunlight reflected off dust particles opposite the Sun. Saturn was a week away from being at opposition here, so it was close to the solar opposition point.
The Summer Triangle stars, Deneb, Vega and Altair, are at centre, with Vega the brightest of the trio and Altair to the south below centre.
The variation in colours along the Milky Way is evident, from bluish at top — toward the outer Perseus Arm — to more reddish at centre overhead, where we are looking toward the nebula-rich star-forming regions of our own Cygnus Arm — to more yellow toward the core area at bottom in Sagittarius, where we are looking through more interstellar dust that absorbs blue wavelengths from the inner arms of our galaxy.
Technical:
This is a stack of 4 x 4-minute exposures with the TTArtisan 7.5mm f/2 fish-eye lens stopped down to f/2.8 on the stock Nikon Z6III at ISO 1600, on the MSM Nomad tracker. The lens is made for use on cropped-ftame APS-format sensors,
