Jupiter in color

I have obtained three images with red, green and blue filters. Then I have composited them using Gimp.
Here the three images and the final result.

Jupiter and Mars

As Mars is running towards the opposition and yesterday night we had a good seeing, I tried to take some picture of the red planet. While waiting it rising up, I started to practice with the 3x barlow lens. I know that it is too strong for my C8, bringing the focal length from 2m to 6m! It is quite impossible to focus correctly...
Anyway these are the results:
