The sky over Lake Ontario was busy on the evening of 19 August 2012. A stacked star trail image composed of 100 exposures at 30 seconds each. Looking north-east from the Hamilton Beach strip. Polaris is at the centre of the arcs, out of the frame past the upper left corner. The sky glow from Toronto and Mississauga dominates the lower portion of the image. Captured with a Nikon D800 camera and 24-110 mm zoom lens at 24 mm.
A short number of individual 30 second exposures went into this stacked image of the western tip of Lake Ontario, photographed 19 August 2012. Polaris is visible in the upper left corner of the image, as the bright star that moved the least. Several aircraft cut across the sky, and the lights of the conurbation on the north shore are reflected – and smoothed out – in the multiple exposures of the water.
The stars make arcs in the sky in long exposures. This image was composed from about 120 individual wide angle photos taken with a Nikon D7000 on a tripod, on 14 August 2012. The technique is sometimes called “stacking” and this one was assembled with free software called StarStax.
