8" LX200. Canon A510
1 second exposure at 400 ISO
5X detail of the same pic.
I don't know if the brightness differences are actual albedo features or to what degree are just image artifacts. The use of the camera's optical zoom, which worked better than using a barlow introduced some chromatic aberration which was toned down in post-processing. Also the image was rounded since it was slightly elongated to begin with.
Alas, I also attempted to image Neptune but had no luck getting it to register at all. I may try again another night.
What surprised me visually about Uranus is how strikingly non-stellar it is even at low power. It is a crisp, steady, light -- akin to an LED. It should be easy to distinguish against a starfield if you know where to look. Not quite the case with Neptune though.
