This evening the sky was finally completely clear, so I managed to take a few nice shots of the comet again. I made the zoom-in below by averaging 9 individual 1 second exposures (as I have no motorised equatorial mount to track the comet, I can not use longer exposure times with the focus set to 200 mm, because the sky turns too fast). It was barely visible with the naked eye.
The star positioned towards the top right from the comet is 51 Piscium, and the apparent distance of the two objects was 21.5′, or 2/3 of the apparent diameter of the Moon. And below is a more wide-angle look (aka, the full image at 200 mm a bit earlier during twilight).
