Jupiter and Saturn, Great Conjunction, 2020-12-20
I reprocessed some other data from this night for better color balance. The star next to Ganymede isn't visible in the new version, but overall it looks closer to the ideal view through a telescope:
Jupiter and Saturn, Great Conjunction, reprocess
Taken with the 14" Celestron SCT at Cerritos College, this image is a composite, as there is no way to expose both Jupiter and Saturn at the same time and get this level of detail in both planets. A 0.63x focal reducer was used with a Skyris 445C camera to capture 800 frames for each stack. The exposure for Jupiter was about 1/5 the duration per frame as the one for Saturn. AVI files were stacked in AutoStakkert3, then processed in PixInsight and Photoshop. Photoshop was used to place the properly exposed image of Jupiter in place with Saturn and the Galilean moons.
The Jupiter AVI was from 2020-12-21 0120 UT, and the AVI for Saturn and the Galilean moons was from 0123 UT. From left to right, across the bottom, are Callisto, Ganymede, Jupiter, Io, and Europa.
