I Tried Again to Process That Jupiter Image

I shared a very ugly image of Jupiter a few days ago.  I tried again.

I have not tried imaging the Galilean satellites since 2014. (I forgot that I had done so because of a stroke a month or so later.) Anyway, I went out the other night to try again. I got a nice image of all four.

Of course, Jupiter at 1 second was grossly overexposed.

So I took 11 seconds of video, ran it through Registax, cropped the image and ended up with a very crude version of what I saw through the eyepiece. I am not sure what exposure time I used; EXIF does not provide that for video. Comparing the brightness to stills suggests 1/50th of a second.
