I was fortunate with the moon have just set to make 100 x 30 sec captures of this topical comet as it passed through Leo. Others are more experienced than I am and may have had the opportunity to image bigger, more dynamic comets. But this is one of the best ones for me with a very distinct ion tail and a barely visible dust tail. The one at 10 o'clock is the ion tail, The dust tail is at about 7 o'clock. The comet was naturally moving in line with the dust tail from the bottom centre of the image and upwards to the right...towards 1 o'clock. If you miss this one you'll have to wait nearly 1000 years for its return.
The small galaxy in the upper centre of the image is NGC 3429.
