The area around the head of Scorpius, including the bright star Antares at lower left of centre and the dark lanes leading to the star Rho Ophiuchi. The area is filled with colourful nebulosity, including yellow and blue reflection nebulas and magenta emission nebulas. To the right of Antares is the globular cluster Messier 4. The field is similar to what binoculars would take in. I shot this the morning of May 5, 2014, from the Four Bar Cottages near the Arizona Sky Village, near Portal Arizona. This is a stack of 10 x 3 minute exposures at f/2.8 with the 135mm lens and Canon 5D Mark II (filter modified) at ISO 1600. The camera was tracking, but not guiding, on the iOptron SkyTracker. Stacked with Median combine to eliminate satellite trails.
The multiple star Sigma Orionis, near Zeta Orionis and Orion’s Belt in the constellation of Orion. Captured with the Sony a7III in a stack of 9 x 8-second unguided exposures at ISO 1600 with the Celestron C9.25 inch SXCT at f/10 on a moonlit night.
