M6 and M7 Area (77mm 5DII).jpg
The two Messier open clusters, M7 (left), Ptolemy's Cluster, and M6 (right), the Butterfly Cluster. M7 is embedded in the bright star clouds of the Milky Way while M6 is in the dark lanes.
I shot this March 30/31 from Coonabarabran, NSW, Australia, using the Borg 77m astrographic refractor (330mm focal length) at f/4.3 using a stack of 5 x 8 minute exposures with the filter-modified Canon 5D Mark II at ISO 800.
