High-resolution global Neptune mosaic with Great Dark Spot
This mosaic is composed of approximately 20 images taken through green or clear filters about 2 to 3 days prior to Voyager 2's closest approach. It has been colorized with lower-resolution data taken from farther away.

For more information on how this mosaic was made, read this blog post.

Here is a version of the image with greatly enhanced contrast and the effects of global illumination removed:
