Hi to all, this is not a recent observation but I am new to the forum and the subject is quite unusual. This has been the first time I've had the impression I could see details on Uranus. Very tough subject and observation though. Credits (if the features are real) to the 10" Clark refractor at Bethany obs., CT. Intensity estimates were made according to the BAA scale (10=dark, 0=very bright).
Comments are welcome, especially if someone has experience on this remote planet.

I forgot to add that the dark "belt" in the color drawing on the left has definitely more contrast than in the real thing

That's excellent! I haven't spent much time with Uranus, but I guess I should. You got good results with a #58 filter?

You are the first I know who managed to see detail on Uranus! Impressive observation.

I've never spent much time on Uranus either, for the same reason as you :crazy: That night I was done with Jupiter and had time before Mars came up, and I had that big refractor so...

I didn't even know which "side" Uranus was showing to the Earth, but I checked later at home and it seems consistent with my drawing, so I thought that I could have seen right.

Getting the best result with a filter depends on what you are interested in I think; my remark about the W58 only relates to the visibility of the bright band but yes, I could see it best with a W58, even though it was visible with blue, red and yellow filters too (end even without).

That is excellent Ivano. I haven't had the chance of looking at Uranus yet. Thanks for sharing. Can't wait to see more.

Wow! That's impressive. I do not think I have seen detail in more years than I can remember. Any way it has been a long time.

Ivano,

Outstanding observation of Uranus. Seen her one time and I guess I owe the planet a detail observation. Perhaps I'll sign up for a night for our club's 8" Clark/Brandt Refractor.

Hi, if you happened to observe Uranus from time to time I'd be glad to know more.

I agree with everyone. Nice work and I didn't know one could observe features on the disk. Thanks for teaching me.

I have looked at Uranus a couple of times this year but only having a disk thats 3 seconds in diameter, well all I have seen is a very small blue-green disk. Many years ago when Uranus was much closser I have seen detail similar to the posters sketch.

Thanks, Buddy
