Thank you everyone for your comments and questions.
The exposure time was recommended by the class instructor. As the sun set, I changed the exposure times but stuck with the original recommendations.
The lens used for the shots was a Nikkor AF-S 16-35 1.4 G ED. My favorite wide angle.
I did not know what the store original option was, thank you for letting me know. I have now uploaded the original.
Thank you again.
And now we can see the plane that created the contrail! Thanks.
