It’s been mostly cloudy here during the early evenings for the last few weeks. I got the chance on 12/19/2020 to get Jupiter and Saturn in the same image frame using a 0.5 focal reducer, but the captured and stacked images looked poor. It was very windy. Today was conjunction day 2020 for Jupiter and Saturn, and it was snowing and windy most of the day. The clouds parted at about 4:45pm. I first observed Jupiter and Saturn visually with a 10mm eyepiece. The image posted is the closest in time to the eyepiece view, and the highest elevation. I will try to recover the moons of Jupiter and Saturn with more processing. That less than one hour of time this evening was a memorable experience. Thanks for taking the time to view this post.

Celestron C90 (F11), prime focus, IR cut filter, ZWO ASI224MC, SharpCapPro3.2, AutoStakkert!3
Image capture starting at 23:34.01UT on 12/21/2020, 1304x976, RAW8, used ROI box around Jupiter for histogram (about 70%), stacked 19% of 2473 frames
12/22/2020 Update: After using RegiStax to change the minimal sharpening, I used GIMP to brighten Io and Ganymede just enough to register. Callisto and Europa also appear in the original capture file when working with RegiStax, but they're dim. The attached image is the original submission from yesterday.
