After finishing with Mars, the seeing had dropped off a bit by the time Saturn rose above my walnut tree, but was still better than average.

Took a long (4.5 minute) L channel, and three 1.6 minute RGB channels to get this LRGB composite to cap off a good night of planetary imaging.

Thanks for the comments.

At the end of the session I took some overexposed video without the powermate to get the moon positions.

Shows how amazing the human eye is. I had to stretch the histogram of the stacked image two ways to get both the moons and the planet. The final image is a composite, as Saturn is hopelessly burned out if the moons are visible.

Through the eyepiece, no problem seeing both at the same time.

Thanks Ray, I was able to stack about 2400 out of 8000 frames for L, so it came out pretty smooth even though the gain was pretty high.

Good stuff Ivan! I too will stretch my stacks/RAW data looking for moons. I've got 10 nights worth of Saturn data where I COULD make composite Saturn/moon images if I could be bothered, lol.
