Imaged Saturn last night,targeting the dark oval in the NNTrZ.
Have 2 R,2 RGB & 1 742nm IR data sets over a session of 90 minutes. The seeing was fair.
The dark oval is clearly visible in all data sets. In the first R & RGB images the bright spot that has been leading the dark oval in the NNTrZ is also visible but the distance between them is stretching out noticeably. I suspect the position of the bright spot,being a little further North,is experiencing the stronger winds in the jetstream of this region. I also note a bright spot in the NEB,just leading the dark oval.
Have also attached animations of the R & RGB data which show the movement of the dark oval quite well. Have also attached polar projections of all data.

Seeing was Fair. Nice night out under the stars with my AP 10" maksutov. Fair image FYI.
