I finished my first good image of Uranus.
Planet is colorized from three filtered images (orange, green, blue). Slightly brownish color of rings is entirely artificial. -------------------- |

If you haven't seen it, you should check out Bjorn Jonsson's version of a Voyager Uranus image, posted with lots of his comments about processing. The key thing of interest in reply to antipode's post is that he found no features in the images that were significant enough to make it worthwhile to rotate the three frames in 3D space to align them before creating the color composite.
Also, regardless of whether Argo is selected, I think Neptune will be visited again before Uranus, because of Triton. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

The key thing of interest in reply to antipode's post is that he found no features in the images that were significant enough to make it worthwhile to rotate the three frames in 3D space to align them before creating the color composite. This is different from my Jupiter, Saturn and Neptune processing where I usually rotate the images in 3D space. For Uranus I didn't see the need for that as the features are very low contrast in OR, even more low contrast in GR and not visible at all in BL. Uranus is no less interesting than Neptune in my opinion. Being visually bland doesn't make a planet uninteresting, it just makes it more difficult to explore. Comparing Uranus and the other the other big 3 there are interesting differences, for example Jupiter, Saturn and Neptune radiate significantly more energy into space than they receive from the sun while Uranus doesn't - it radiates hardly any excess heat. And with the exception of Triton, Uranus' satellite system is actually more interesting than Neptune's. Comparison with the Cassini results at Saturn would be interesting. I have sometimes been a bit frustrated that Voyager 2 couldn't be launched a bit later (or technology developed faster) because then it could have carried a CCD camera sensitive to near-IR. The amount of visible details increases greatly with wavelength (comparing OR and BL there is a big difference) so I suspect Uranus would look highly interesting to a Cassini (or even Galileo) style imaging system in the near-IR. Probably highest resolution image of Uranus with some details (~12 km/pix). Color from green, violet and synthetised images. This is extremly interesting, possibly the most interesting Voyager 2 image I have ever seen of Uranus. Now I wonder if there are any images of comparable resolution extending further 'down' and thus showing the bright feature better... |
