Here's a sketch of Gassendi. It was buried deep in the terminator at the time and was barely resolvable with the naked eye. The equipment was a 130mm F/5 at 108X. The FOV is approx 1.5'. Unfortunately, the tracking isn't working properly
so I am tracking by hand which makes it much harder to draw. I would have liked to get more detail but I lost an hour photographing a distant lightning storm and found magnifications above 100 too hard to use with the hand tracking.
