The galactic centre region of the Milky Way in Sagittarius and Scorpius, over the upper field of the Texas Star Party, near Fort Davis, Texas, May 13, 2015. About 600 people gather here each spring for a star party under very dark skies near the MacDonald Observatory. Sagittarius is left of centre and Scorpius is right of centre with the planet Saturn the bright object at the top edge right of centre. The dark lanes of the Dark Horse and Pipe Nebula areas lead from the Milky Way to the stars of Scorpius, including Antares. The semi-circular Corona Australis is just clearing the hilltop at left of centre. This is a composite of 5 x 3 minute exposures with the camera tracking the sky for more detail in the Milky Way without trailing. Each tracked exposure was at ISO 1600. The ground comes from 3 x 1.5-minute exposures at ISO 3200 taken immediately after the tracked exposures but with the drive turned off on the tracker. All are with the 24mm lens at f/2.8 and filter-modified Canon 5D MkII camera. The ground and sky layers were stacked and layered in Photoshop. The tracker was the Sky-Watcher Star Adventurer. High haze added the natural glows around the stars — no filter was employed here.
An observer at the Texas Star Party aims his telescope at a target in the Milky Way. Sagittarius and Scorpius toward the galactic centre are to the southeast here, as they rise late on a spring night. This is a single untracked exposure of 45 seconds at f/2.2 with the 24mm lens at Canon 5D MkII at ISO 4000.

Scorpius is rising in the background; Saturn is in the head of Scorpius as the bright star above centre. Anatares is just below Saturn. This is a single 30-second exposure at f/2.5 with the 24mm lens and Canon 5D MkII at ISO 6400.
