Where in Moscow could you have seen the comet yesterday, let alone photographed it? Solid cloud cover.

In the north) So I guess I was lucky. I really wanted to photograph it, and finally, the opportunity came along.

Good evening! At an open aperture, does the lens distort the stars?

Good evening. At the widest aperture, noticeable chromatic aberration appears. In this image, the aperture is fully open, if my memory serves me correctly.
