Hi all,
last week surprising cleard the sky for 1,5 hours.
I found excellent seeing for my 6" f/6 Dobson !

Here two sketches:

5.12.12, 6" f/6 Dobson, Binoansatz
22:05 UT I 207° II 152°
22:50 UT I 235° II 179°

The dark spot behind the BA was(not) visible,
I think the contrast lost the last weeks !?

Bye Christian

Christian, thanks for showing what a 6" can deliver on Jupiter. Lots of stuff to discuss.

One question, though, in the SEB (first sketch.) The white spot should be following the darker spot, do you them backwards or notice another white spot?

Actually, it looks like yo may have actually seen the darker oval trailing BA. Now, there are some tiny, faint features down there, just as you show. There is a bit of a belt preceding the GRS. That belt is slightly north of BA. So, if you saw something behind BA that was not that belt, it has to be the darker oval. I think you may have seen it. And by the way, that belt is not easy either, yet you seemed to have captured it. Well done.

The white ovals in the second sketch indicate you had very good seeing. Well done, again. Those are delicate features, in my experience. Any breath of air and they wash away.

It's nice to know you had an awesome view, and maybe more successful than you imagined.

Wow, Christian. Great sketch work! I'm guessing the seeing settled a bit for you between sketches. Fabulous job picking up those ovals. You are making me less patient to wait for delivery of the last few parts for my 10" scope.

Christian,

A six inch scope is plenty enough aperture to deliver excellent views on Jupiter as you have clearly demonstrated.
Excellent capture.

Frank
