Great idea!
I’ve attempted messier marathons before. Not all objects are visible from here, but some 90 or so are, depending on how good your horizon is. The most I’ve got in a night is about 50, and by then the bed started looking really good 🙂 I rationalised it with the idea of quarterly “mini marathons” since more objects are visible if you observe throughout the year. This hasn’t really happened, but I’ve done a few messier sessions at different times of year. Perhaps we could do something like this at CAS.
Have Fun! Time zones and many observers will make the EVscope marathon more sleep friendly and lots of fun!
