An all-sky aurora with green and purple curtains, the night of June 7-8, 2014, starting up about 12:30 and going until dawn. This shot was near its peak, from the old barn site near home in southern Alberta. The purple colour is partly from blue scatttered sunlight hitting the red tops of the auroral curtains. Cassiopeia is at upper right. This was with the 16-35mm lens at f/2.8 for 20 seconds at ISO 1600 with the Canon 60Da. It is one frame of 280 shot for a time lapse.
A mosaic of the region around the Small Sagittarius Starcloud and Dark Horse dark nebula complex. The field takes in the Milky Way from the Lagoon Nebula at bottom to the Eagle Nebula at top left. In between from top to bottom are the Swan Nebula (M17), and the Small Sagittarius Starcloud (M24). Flanking the bright M24 starcloud are the large open clusters M23 (right) and M25 (left). At bottom left is the M22 globular star cluster. The prominent dark nebula at right is the large Pipe Nebula (B78) with the small Snake Nebula (B72) above it. The whole complex is visible to the naked eye as the Dark Horse. This is a mosaic of 4 panels, each a stack of 5 x 3 minute exposures with the 135mm lens at f/2.8, and with the filter-modified Canon 5D Mark II at ISO 1600 tracking the sky on the iOptron SkyTracker, with no guidind. Images were stacked and stitched in Photoshop CC. Taken from the Four Bar Cottages near Portal Arizona, May 4/5, 2014.
