An observer gazing into the southern stars with a large reflector telescope at the 2014 OzSky Star Safari star party near Coonabarabran, NSW, Australia, March 2014. The Southern Cros and Coal Sack are in the sky behind the observer. This is a single untracked 10-second exposure at f/1.4 with the 35mm lens and Canon 60Da at ISO 3200.
The Coal Sack and Jewel Box Cluster area on the east side of Crux, the Southern Cross. The Coal Sack, which to the eye looks like a large dark patch, under photography breaks up into small patches, the darkest just south of the Jewel Box Cluster, here just below and left of Becrux, or Beta Crucis. Other star clusters in the scene are NGC 4852 at top left, Trumpler 20 at right. and NGC 4609 at lower centre. The cluster at far right above Acrux is NGC 4349. The small intensely red area left of centre is the nebula Gum 46. The star at lower right is Acrux, Alpha Crucis. This is a stack of 5 x 8 minute exposures with the Borg 77mm astrographic apo refractor (330mm focal length) at f/4.3 and with the filter-modified Canon 5D Mark II at ISO 800. Taken from Coonabarabran, Australia, March 2014.
