This image shows you the comet Hale-Bopp after two weeks from my previous observation at a suburb of Tokyo. Unfortunately it was vernal hazy condition and moonlit night, I could not detect an ion tail with naked eyes. However, I could appreciate a bright dust tail clearly; it was widely spread out westward (lower direction in this image) compared with observations in March.
The comet in that day had a heliocentric distance of 140 million km and positioned in Perseus. The comet just started to return to far-space beyond the solar system.
