I had a go at webcamming the Pleiades with my short tube refractor and 0.6 second exposure. Although I (obviously) couldn’t get the whole cluster in, I managed a few runs with more than one star. In some ways the photos looked a bit like close-ups of multiple star systems taken with much larger telescopes. An attempt to stitch them together failed.
I also tried Melotte 20 but could only see Alpha Persei on the screen. However, I was able to capture 2 other stars nearby.
