Saturn on 7/30

 

 
Best 2,685 frames from 22,382.  If you enlarge the image, you might be able to see hints of Encke's Gap?  

Taken 7/30, 11:42 pm.   QHY 290 mono with IR 685nm filter.  Stacked in Autostakkert, Registax and a little sharpening in Gimp.

(After looking at a couple of Saturn images and checking with the original video, I would say about 75% of the clear frames show the right side as slightly elongated.   So most of the time Saturn is not really symmetrical.   Weird.   Is this an optics issue?  My "earlier" Saturn shot from 8/8 shows this same phenomenon.)
