If you observe tails, start at the coma and add the brightest areas first, using small strokes. Again, use the surrounding stars as reference points. Soften the pressure when transitioning to the faded edges. Comet PANSTARRS had a second bright “tail.” This wasn’t an actual tail, but rather an area of reflective dust particles that remained in the comet’s orbital plane. Often referred to as an “anti-tail,” it’s the bright spike we see stretching toward the Sun. I used averted vision to detect the dust tail between the wedge of the ion tail and the anti-tail. I added it by smudging graphite into that area with my blending stump.
End your sketch by adding relevant observing data such as the date, sky conditions, equipment used, and any notes. The more you sketch, the more changes you’ll see when tracking a comet — and best of all, you’ll have a personal record of the visit to remember it by.
