I have not sketched Saturn this go around because of extremely poor weather so far this year. On Wednesday evening the atmosphere cooperated and I had a scope outside cooling down. I did not have access to any Saturn templates because of a computer crash I have not yet been able to repair. So I took out my old mechanical drawing equipment and made an ellipse of the approximate eccentricity of Saturn’s rings and sketched from there. It’s a bit crude but reasonably close to the view. Seeing was good and the atmosphere was transparent. I was able to see Mimas but it was just beyond the way I framed the sketch for posting. Enceladus was about 12th magnitude.
