I took pictures of comet 3i from 5:33 to 5:40 am this morning using my 3-inch refractor at f5. The attached jpg image shows the full field of view and the gif image is cropped and shows the comet's change in position over this time.
The comet is in Leo, which is high in the southwest before sunrise.
My images aren't much to look at, but it's fun being able to capture an interstellar object.
