Note 1: The annotated image shows star labels for field identification purposes.
 
Note 2: The Stellarium file simulates the comet's tail with parameters as follows: dust_brightnessfactor = 1.0, dust_lengthfactor = 15, and dust_widthfactor = 8. The date was set for November 9th to get the tail in the same position as in the photo.—WM
