Thanks Ryan.
Stacking really is a powerful tool and thankfully now relatively easy to do.
Tips....
The bigger the aperture the better, as resolution is a function of wavelength/aperture not magnification.
Shoot a LOT, as you will need to fine tune your image acquisitional skills (really just means refining your focussing technique and getting a good exposure).
Shoot a LOT, so that once you have your technique ironed out, you can improve your odds of getting good imaging conditions.

Awesome images Bob, I want to try this stacking technique someday. Any suggestions for a beginner?

Thank you Stephen.
Yes, these are stacked.
Saturn was processed from about 300 frames (actually from the very first night using a webcam).
In the case of Jupiter, it's the result of about 900 individual frames. It was one stacked image from a 6 hour run, where I shot a partial rotation. After processing, I spliced together the individual stacked frames to make an animation of the planet's rotation which also exhibited the orbiting moons as they traversed the disk of the planet.
Mars is the result of two stacks, the first being 1500 frames through an IR pass filter (~800 nm) and the second, 600 frames in white light. The IR stack was used as the luminosity layer and the white light stack was used for the RGB.

Bob these are fantastic photos, the best I have seen so far on Usefilm. Where they stacked at all ?
