Neptune from Voyager 2. Color is from images with CH4JS, green and orange filter.
Shadows of three moons are visible. Second image is with possible interpretation. -------------------- |

A few recent Neptune projects:
Here's a narrow angle frame from August 20, I think there's a JPL version floating around. However, it still has the scanline artifacts, and is so deeply saturated that it looks like a monochrome image that's been painted a single tone of blue. Narrow angle frame of the Great Dark Spot rotating into view on late on August 23. I did some blending of narrow angle clear and green filter images to get more of the limb in view while retaining some of the sharpness of the cirrus clouds. Color is taken from wide-angle images taken simultaneously. Some of the color noise has been suppressed using the Deep Sky Colors HLVG plug-in. Not super happy with the results but I think it's the best I'm going to get considering the available data. Finally a departing shot of Neptune and Triton on August 31. Dark Spot Jr. is near the cusp on the left, as well as a cluster of cirrus clouds that often popped up over the spot. Dark cloud bands around the south pole are also unusually clear in this image. Not sure why. |
