Eric, they were indeed satellite trails. I always get a kick out of spotting them, as well as meteors, zipping through my FOV.
Frank, that sketch sketch was the first lunar sketch I've done with the 16" that I can remember since I got it last winter. The views are so impressive that sketching with it was intimidating, especially lunar sketching because of the fast shadow changes and how long it takes to do a lunar sketch. After awhile, I was getting pretty good about pushing the scope around with my nose so I could have both hands free for sketching.
It's a pretty good thing I don't have a delicate, cute little nose.
