Hello!
For a white zone, this is quite good. Well done!
The only issue: it seems the focus may have drifted a bit.
Check the focuser periodically. I have the same telescope, and the Crayford focuser on it sometimes needs tightening.

Thank you! Yes, there is such an issue. In this session, I focused only once at the very beginning and didn't notice that the focus had drifted (perhaps due to the weight of the equipment on the focuser, or maybe because of the temperature drop). I plan to purchase an electric motor for the focuser and set up periodic autofocusing throughout the imaging session via N.I.N.A.
