Jupiter & Saturn - Dec 19, 2020 with Labels (SE6-60Da).jpg
Jupiter and Saturn in the same telescope field on December 19, 2020, as they approached their Great Conjunction of December 21, 2020.
The Galilean moons of Jupiter are visible in this exposure, but not the moons of Saturn as this was shot through thin cloud and the planets were so low the blurring was extreme! Even Titan was too faint to show up.
The planets were less than a 1/4 of degree apart this night, with a separation of a mere 13 arc minutes, and closing to half that distance, 6 arc minutes, two evenings later. I've added labels in this version.
This is a stack of 4 exposures with the Celestron SE6 f/10 Schmidt-Cassegrain (so 1500mm focal length), for 4 seconds each at ISO 800 with the Canon 60Da. I had the Celestron SCT on the Sky-Watcher EQM-35 equatorial mount, tracking the sky. The images are stacked to smooth noise. Atmospheric refraction adds the colour fringing to the planet images.
