A telephoto lens image of the globular cluster Messier 5 in Serpens. This is shot to simulate the field of view of binoculars for illustration purposes. This is a stack of 6 x 1-minute exposures with the 200mm lens at f/2.8 and Canon 6D MkII at ISO 800, tracked but unguided on the Mach 1 mount, on April 28, 2019.
M6 and M7 (left of frame) and area off the tail of Scorpius, in a telephoto lens shot that simulates a binocular field of view. Taken from San Pedro de Atacama, Chile, May 2011, with Canon 7D (unmodified) and Canon 135mm telephoto lens at f/2.8 for stack of 6 x 2 minute exposures (unguided on Kenko Sky Memo tracker) at ISO 1250. Stinger stars of Scorpius's tail at right.
The rich region in the tail of Scorpius with star clusters, nebulas and Milky Way starclouds. The area contains the bright star clusters Messier 6 (at top left) and Messier 7 (at bottom left but lost in the star fields). M6 is the Butterfly Cluster, and M7 is Ptolemy’s Cluster. The bright stars at lower right are Shaula and Lesath in the tail of Scorpius. The nebulas at right are NGC 6357 (top) and NGC 6334 (bottom), aka the Cat’s Paw Nebula. This is a stack of 5 x 2-minute exposures with the 200mm lens at f/2.8 and filter-modified Canon 5D MkII at ISO 1600. Tracked on the AP 400 mount, unguided. From Tibuc Gardens Cottage.
