Saturn July 2nd dark oval, in good seeing ?

Hi All,

Imaged Saturn July 2nd. This really was just an afterthought. I had to drive to Adelaide very early the next morning ( a 6 hour trip) and the seeing was predicted to be rather ordinary. As it turned out, the transparency was very good and the seeing was quite interesting. Always nice detail but with a high frequency oscillation, from time to time. It was hard to rate the seeing, I only stacked 40% of the data but that 40% was quite good.


I returned to Broken Hill today July 6th and have just finished processing.

Have captured the dark oval, it continues to drift at approx 3.4 degrees in L3 per Earth day. Have also captured some interesting features in the NEB which are best seen in my R channel animation. The polar hex is very well defined in my R & RGB polar projections, as is the dark oval.


Have attached 1 R, RGB & 742nm IR data sets along with 1 set of R, RGB & IR polar projections with R & RGB animations captured over a 1 hour session.

Thanks for looking.

Regards
Trevor
