Visibility II / V
The 22° ring section, which stood out to the eye quite modestly, got the stilts moving again and I grabbed 81 photos to stack the set.
Apart from the basic tire and the 46° tire, nothing else has come off. Some foreboding edge in the average stack outside the double is ghosting, but not convincing until the rut.
What confuses me is the change in the radius of that 46-ring, which is quite noticeable from the stuff in the maximum stack. On the left side, the tire falls out of the frame and on the right "stays on". In fact, something similar can also be observed in my previous observation from the same field. Where is the problem, in the eyes, in the equipment, in stacking or in some other aspect?
Figure 1. The maximum stack, Figure 2. the same color channel processed and Figure 3. the color channel processed version of the average stack.

Omassa päässä tuo nelikutosen heitto lähti nyt selittymään sillä, että peittäjä oli aavistuksen kuva-alan keskilinjasta sivussa molemmissa tapauksissa.
Laajiksella kun nurkat tuppaa muutenkin vääristymään, niin tuollainen pieni heitto keskilinjasta riittänee aiheuttamaan kaaren aukeamisen vastakkaisella puolella.
