2015 I had the idea to do a moon time lapse, the moon is here up for 2 weeks and down for 2, so it goes through half its phases when it is above the horizon. Besides the North Pole (or at least close to it) that are the only places where you could do a time lapse like that. So I rebuild an old amateur telescope mount, which would work in the cold, with an arduino and a stepper motor to track the moon. But the only time the time lapse will work is right at sunset or sunrise, because exposure has to be short enough to actually see the phase of the moon. First try was in 2016, the second one last year, which didn't turn out because of bad weather.
So I tried again this year, weather was mostly good, but I had some problems with the tracking mount, which is needs to run flawless for 2 weeks at temperatures below -60°C. Unfortunately it got stuck a few times :( but since then I replaced a faulty part of the drive and hopefully it will work better at sunrise or last chance next year.
But here is the video from this year, watch the changing phase of the moon from nearly full to a very small crescent.
