Below is picture of Jupiter I took the other night (Sept 21 at 19:54 PST). This image was made by stacking ~1400 frames of 4K video with the freeware program Registax 6. I took the video using a canon 5D MarkIV connected to a Celestron 11 inch Schmitt Cassegrainian telescope. The image shows Jupiter and it's 4 Galilean moons (you made need to download the image to see the moons). Going left to right is Callisto in the upper left of the image followed by Europa, Io, Jupiter, and Ganymede in the lower right of the picture. During the processing I had to lighten the moons to make them visible relative to Jupiter. Jupiter is getting lower in the night sky as we get into fall so atmospheric turbulence is getting worse, but there is still some detail that can be pulled out of the image with stacking. This image of Jupiter isn't quite as crisp as one of my previous posts due to atmospheric turbulence but does show the 4 Galilean moons and Jupiter's red spot).
The next shot of Saturn was taken in a similar manner using ~1100 frames at 20:15 PST. The image of Saturn was cropped to enlarge it since there wasn't anything else of interest in the image.

...these are excellent...from the red storm on Jupiter to the shadow of the planet on Saturn’s rings...very well done...!

Compared to the shot of Saturn I took back in July you can definitely see the difference in perspective with the shadow of the planet on the rings as Saturn and Earth change location in their orbits. See image from July below.

Very well done. With my 4" refracter I am able to see Saturn's rings, and the void between the planet and the rings. I read recently, the rings are temporary. If our stage of mankind was half a million years earlier or later the rings would not exist. Even it the short time we have been able to measure them they have changed, losing material. The concept of time is fascinating to me.
