Selfie Shooting Great Conjunction with CU Inset (Dec 20, 2020).jpg

A selfie shooting the "great conjunction" of Jupiter and Saturn on December 20, 2020, the night before the closest approach of the two planets, seen here in the distance over the peak. The inset shows the closeup view captured by the telescope a little earlier in the evening, with the two planets and their brightest moons labelled.

The planets were less than 1/8 degree apart (8 arc minutes) this night, on a perfect night at Dinosaur Provincial Park, Alberta. They were 6 arc minutes apart the next night but clouds prevailed!

I am shooting the planets with a Celestron SE6 tube assembly on the Sky-Watcher EQM-35 mount and with the Canon 60Da cropped frame camera, for maximum magnification.

The background selfie is a blend of two exposures, one focused for the background and sky, and one focused for me and the telescope in the foreground, both single 1.3-second exposures at f/2.8 and with the Canon 35mm lens and Canon 6D MkII at ISO 400. Another camera for shooting tracked shots is in the distance at left.

The closeup inset is a blend of short 0.5-second (for the planets) and long 3-second exposures (for the moons) with the scope at f/10 for 1,500mm focal length.
