Here is a series of photos of Comet Hale-Bopp taken from the north shore of Oahu, Hawaii, about 6 days after perihelion. The photos were taken at approximately 20:15 on 6 April HST (06:15 April 7 UT).
1. Watching Comet Hale-Bopp, under a palm tree at the beach.
Camera: Mamiya 645 Pro Lens: 45mm f/2.8 (@f/2.8) Film: Fuji Provia 400
2. Here is a close-up view of the comet. The diffuse dust tail and the narrower blue ion tail are both clearly visible. The ion tail is shaped by the solar wind and points almost directly away from the Sun. The dust tail has a more curved shape, caused by radiation pressure from the force of the light that the dust particles absorb. The dust particles follow trajectories that are a combination of their orbital inertia and the outward push from the sunlight.
