About this image

Difficult meteorological conditions before clouds rolled in. Fortunately I was able to take a stack of 42 images of the dusk sky and used these to perfectly flatfield those of the comet. Using a fast lens makes the flat all-important. Will upload a view of the flatfield separately.
