Reduced the working distance, it turned out to be 58mm, to 56 and the stars became more or less, but still the left corner is a bit crooked. And I inserted a lens hood in front of the corrector (like a carrot), the background became even, otherwise the lanterns are shining and illuminating the top of the tube.
A very strong wind was blowing and the sky was not promised for long.
