All-Sky Milky Way Looking South - Naked Eye View (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. I have processed this version to simulate the sky as it would have looked to the unaided eye — mostly monochrome and with lower contrast than in most long-exposure and processed color images.
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.
Even in this naked-eye simulation, the dark dust lanes along the Milky Way stand out, such as the dark Funnel Cloud Nebula above center. On a dark night such as this it stands out as looking darker than the rest of the sky. Also visible are the bright star clouds along the Milky Way., such as the Cygnus Starcloud at centre overhead, and the Scutum Starcloud at lower right. The bright galactic core area and the Sagittarius starclouds are above the southwest horizon at bottom right.
At upper left is the Andromeda Galaxy, Messier 31. It is naked eye as an elliptical glow just like this.
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.
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, but works well on full-frame cameras
