The MSM low-cost tracker being polar aligned with the laser pointer option. Illuminated with red flashlight. Nikon D750 and Sigma 24mm lens, from home August 18, 2019.
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.
