December 23, 2020 Jupiter Saturn Great Conjunction

As expected, the weather this evening is almost clear and together with my son KC, we were able to image again the Jupiter and Saturn Great Conjunction. The separation is now slightly a bit farther than the past 2 days and this will probably be my last documentation of this conjunction.

I initially use my Borg 76ED refractor with Canon EOS M6 mirrorless camera at prime focus of 500mm f/6.5 to image the event but seeing the weather is a bit forgoing, we opted to switch to the Celestron C90 Maksutov-Cassegrain with an effective focal length of 1350mm f/13.8 on the Canon EOS M6 mirrorless camera to get more amplification and it was again mounted on my old reliable Vixen GPDX mount.

Wide field image was taken using Huawei P40 Pro at 27mm (35mm equivalent) at f/1.9 with 1/20 sec exposure at ISO 3200. Close up were taken using Celestron C90  Maksutov-Cassegrain with an effective focal length of 1350mm f/13.8 on the Canon EOS M6 mirrorless camera at 1/30 sec exposure at ISO 800 while the overexposed Saturn and Jupiter with Jovian Moons were exposed at 1/8 sec exposure at ISO 800.
