A bit of a strange night for me, it was very still, very clear, jetstream values not too high (in the mid 30's m/s), but the focus shifted around more than I would normally like. However, it was good enough for long enough to capture some good images of Jupiter and Saturn near the meridian (which meant derotation was a must, if only to remove the field rotation).
Lots of images to choose from, but I've chosen these, Jupiter with the GRS front and centre, a 10 minute video derotated in WinJupos and processed slightly differently; I backed off on the Unsharp Mask (could easily have gone higher), increased the midpoint level to 1.1 and added a touch of warming filter in Photoshop (yes, I know, I know, but my "add 10% blue" rule is arbitrary anyway ). Best 10000/90000 frames stacked in AS!3, processed in Registax and Photoshop, shown at 150% captured size.
Saturn was an afterthought, a 5 min video derotated in WinJupos, best 7500/30000 frames stacked in AS!3, processed in Registax and Photoshop, shown at 150% captured size.
