Saturday night (2020-11-21) I recorded LRGB data of comet C/2020 M3 ATLAS. Upon inspecting the image data, I detected a spinning movement of the comets nucleus. To show the movement, I combined the 34 individual LRGB images (240 seconds each) to one stack with the comet forming a curving trail.
During the course of 142 minutes, the comet moved 470 arcseconds (3.3 arcseconds per second).
Last night I had to travel to Vienna. Fortunately I had to pass the eastern foothills of the Alps. As the motorway already went up to almost 1000m a.s.l, it was a 10 minutes detour to reach a dark place above the persistent and annoying fog layers (which are typically at 600 to 1200m a.s.l and quite frequent in autumn and winter).
I had packed my AZ-GTi travel mount, 72mm f6 APO and Sony A6400 as super lightweight and quick setup combo. I could capture almost half an hour of data, before the fog climbed up the hill. Unfortunately the amount of data was too low for good noise base. But anyway – as a first and quick result, it is very well pleasing 🙂
