Canis Major and Puppis, taken from Coonabarabran, NSW, March 2008, with Canon 20Da and Canon 35mm L series lens at f/2.8 and ISO 400 for stack of 2 x 4 minute exposures + 2 x 4 minutes with frosted filter (those frames Lightened stacked to add glows around stars).
The constellation of Canis Major, the large hunting dog of Orion the hunter. The binocular open star cluster Messier 41 is at centre below Sirius. The pair of star clusters, M46 and M47, are at left. The bright star is of course the Dog Star, Sirius. This is a stack of 2 x 2-minute exposures with the 50mm Sigma lens at f/2.5 and Canon 5D MkII at ISO 1600, plus an additional exposure through the Kenko Softon filter layered in to add the star glows. Taken from Quailway Cottage in Arizona, with the Star Adventurer Mini tracker.
The constellation of Canis Major, including the bright star Sirius, and below it, the open cluster M41. At bottom is the loose cluster/asterism CR 140. This is a stack of 6 x 4 minute exposures at f/2.8 with the Sigma 50mm lens and Canon 60Da at ISO 800. I shot this from Coonabarabran, Australia with the constellation straight overhead. I used the iOptron Sky Tracker. High cloud added the natural glows around stars - no filter was employed here.
