Here's my first sketch (well, it's actually 2 sketches and I forget which one I made first). This was last summer when I was able to pick out all the stars of Scorpius. Once I had identified the scorpion's tail and had it lined up in the scope, I made a run for M6 and M7. I couldn't tell them apart, so I sketched them and then verified which was which after I went back in. This is in a 5" f/8 reflector with a 26mm EP under bad summer haze.
Here's M6 (there's a small sketch of Jupiter on there too):
