I used a 200/1600mm Dobson from a good friend. I saw different darkness inside the GRS ! The BA was not strong in contrast. I measurded his position at II 170°. 30.10.2012, 22:50 UT, V 178x and 213x without filter I 305° II 164° I measured the GRS after sketching again by II 183° !

Outstanding. Yea, I see the same thing, but not sure if it's GRS detail or a contrast effect caused by the brighter band across the GRS. To me, the GRS has a two toned appearance at lower power. I did manage the entire oval form at 300x, but did not note any internal features at that magnification. Nice observation, Christian. Bye.

I saw for several years darker parts inside the GRS so I think it´s yet real too. Jef, You got the good weather from West in Belgium mostly hours before it come to me . Sharpen your pencil and take Your redlight and a paper . Bye Christian Edited by Heidescoper (11/01/12 07:58 AM) Post Extras:       Chopin Canis Insanus Reged: 02/03/05 Loc: In the doghouse.

I very much enjoy the shading you've managed to see in the GRS. You make me wish I had better seeing conditions.

A very good luck at Oval BA and the super storm GRS. You saw a little of the turbulence following the GRS, too. Your timing of the GRS at 183° matches the latest S&T info (184°). Super storm Sandy has put a stop to astronomy here. We still have clouds and plenty of turbulence.
