Last night I was sketching the moons of Saturn under average seeing and transparency from a rural dark sky location (Moon kinda made that moot anyway). When I got home I found several tools that allowed me to identify Tethys, Rhea, and Titan easily. However, none of these tools showed Iapetus. Theoretically I think it is in one of its brighter phases (maybe 10.2 / 10.3?) and I could see several dim objects in the vicinity. I marked them on my sketch but can't find anywhere that allows me to compare them against the position Iapetus should have been found. I'll try to attach my sketch from last night (note that the two Messier objects were sketched later at home under worse conditions).
