The arc of the auroral oval across my northern sky from home in southern Alberta on August 4/5, 2019 during a Kp 5 level display at times this night. Later this night the aurora did expand to fill much of the sky. The Big Dipper is to the left, Polaris is at top, and Perseus is to the right. Capella is the bright star amid the aurora. The Pleiades are just rising at far right. The Andromeda Galaxy is at upper right. This is a 3-segment panorama with the 15mm Venus Optics lens at f/2 and Sony a7III at ISO 3200 for 20 seconds each. Stitched with ACR.
The constellation of Draco the Dragon winding between the Big (left) and Little (bottom) Dippers. Polaris is at bottom. centre The head of Draco is at top right. This is a stack of 4 x 1-minute exposures with the 24mm Sigma lens at f/2.8 and Nikon D750 at ISO 1600, plus an additional 1 min exposure through the Kenko Softon filter to add the star glows. All tracked on the MSM SiFo Tracker from China. Taken from home July 24, 2019. Gradient Xterminator, along with gradient filters in ACR, did a good job eliminating sky gradients as the Big Dipper was low in the northwest toward light pollution. Taken in summer but I turned this 90° for a horizontal orientation that is more like a spring sky setting, with the Big Dipper above the Pole.
The constellation of Ursa Major, with the Big Dipper or Plough, photographed in deep twilight on May 27, 2019 from home. I shot this before the sky gat completely dark but before this area of sky got too low in the northwest. At bottom are the line of paired stars called The Three Leaps of the Gazelle. This is a stack of 3 x 1-minute tracked exposures with the 35mm lens at f/2.8 and Canon 6D MkII at ISO 800, plus a similar exposure blended in but taken through the Kenko Softon diffusion filter to add the star glows. GradientXterminator filter applied to even out twilight gradients.
