 This is my first attempt to photograph the planet Uranus, a very distant outer planet with a mere 3.6" disk size. The top image here does reveal its greenish color, and is at a size that the full moon would fill the entire frame. Visually the disk was obvious and yellow green in color.

The lower image was with a 3x barlow, and the seeing was not sharp enough to show a clean disk, but the green color once again is pretty obvious. So much for my first attempt. 500 to 1000 frames were registered and stacked in Registax to make these.
