And here is the second sketch from last night. Originally, I wanted to sketch some Messier globular cluster in Ophiuchus but it felt hopeless when I looked at them through 142mm Dobson. I checked nearby planetary nebula NGC6309. It looked like a wider nebular line pointing to nearby star at north. With averted vision, there seemed to be two brightenings on the line. Here is the rough sketch from the logbook (you can see older Jupiter sketch shining through the other side of paper)
