Saturn from the morning of July 25, 2025. This time I used 7 series of images of 5 minutes each between 1:59-2:44 UTC. Usage rate 10 %, each series individually stacked and sharpened and these sum images again stacked and sharpened. The result includes approx. 5000 frames. I use an exposure time of 40 ms with a gain of 3000 out of 5000. I have also tried shorter exposure times with a higher gain, but the results are not better, they are noisier.
