I like the second one better Jeanette. You are definately improving with each image.
JFYI Looks like you might need to up the gain or gamma a bit next time though, so you don't get as much limb darkening. What do you use to crop your images with. Is it done automatically by a program or do you do it manually. If manual try leaving a bit more sky around the image. That will help present it better an you might find that part of the darkening is an optical effect on having the planet so close to the white webpage background.
