Arcturus and the Napoleon's Hat asterism

This is my second attempt at this - and it shows the different images that can be obtained with different cameras. Compare this with my image from 2016 in this gallery, when an astro-modified Canon 1100D was used.

North is to the top.
This image shows the result of including a first magnitude (mag -0.05) K-class star in the same field as those of mag 10-11. The seven asterism stars to the below right of Arcturus range between mag 9.44 and 10.65.
The brightest star between Arcturus and the asterism is CN Boo, a star variable between 6.24 and 6.27, and TYC 1472-1427-1 at mag 5.99.
